Optical coherence tomography OCT scanner: Overview, Uses and Top Manufacturer Company

Introduction

Optical coherence tomography OCT scanner is a noninvasive imaging medical device that creates high-resolution, cross-sectional “slice” views of tissue using light. In most hospitals and clinics, it is best known as a core ophthalmology tool for evaluating the retina (back of the eye), optic nerve, and macula, but related OCT technology also appears in other specialties (for example, catheter-based applications in cardiology vary by system).

Why it matters operationally: Optical coherence tomography OCT scanner supports fast, repeatable imaging that can improve clinical decision-making, longitudinal follow-up, and multidisciplinary workflows (ophthalmology, diabetes clinics, neurology, emergency pathways, and pre/post-operative assessments). It is also a data-heavy hospital equipment category: image quality depends on operator technique, patient cooperation, device calibration, and robust IT integration (storage, reporting, and cybersecurity).

This article is designed for two groups at once:

• Learners (medical students, residents, and trainees) who need a clear mental model of what OCT is, what it shows, and common interpretation pitfalls.
• Hospital teams (clinicians, administrators, biomedical engineers, procurement, and operations leaders) who need practical guidance on safe operation, infection prevention, maintenance readiness, troubleshooting, and purchasing considerations—without brand-specific assumptions.

The content is informational and workflow-oriented. Local protocols, supervision, and manufacturer instructions for use (IFU) should always govern real-world practice.

What is Optical coherence tomography OCT scanner and why do we use it?

Clear definition and purpose

Optical coherence tomography OCT scanner is a clinical device that uses reflected light and interferometry (a method of comparing light waves) to generate cross-sectional images of tissue microstructure. In ophthalmology, it is often described as “optical ultrasound” because it provides layered images—except it uses light rather than sound.

The core purpose is to visualize and measure tissue layers and boundaries in a way that is difficult or impossible with routine examination alone. OCT supports documentation, baseline assessment, longitudinal change detection, and communication across care teams.

Common clinical settings

Optical coherence tomography OCT scanner is commonly used in:

• Ophthalmology outpatient clinics (retina, glaucoma, cornea/anterior segment, neuro-ophthalmology)
• Hospital-based eye services and emergency eye pathways (triage support varies by facility)
• Diabetes and endocrine clinics where eye screening pathways exist (workflow varies by country and model of care)
• Pre- and post-operative assessment settings (for example, cataract surgery planning pathways often include macular assessment protocols)
• Research and teaching environments (image-based teaching files and clinical trials)

Key benefits in patient care and workflow

From a patient care perspective, OCT can:

• Provide rapid, non-contact imaging in many standard eye-care workflows
• Support earlier recognition of structural changes (clinical significance depends on context and interpretation)
• Enable quantitative tracking over time (trend analysis, with limitations)

From an operational perspective, OCT can:

• Standardize documentation and improve handoffs (when integrated into reports and the electronic medical record)
• Reduce reliance on subjective descriptions alone by adding reproducible imaging
• Support protocolized pathways (for example, referral triage and follow-up intervals) when governance and training are strong

Plain-language mechanism of action (non-brand-specific)

Most OCT systems send a low-power beam of near-infrared light into tissue and measure how much light reflects back from different depths. By comparing the reflected light to a reference signal, the device calculates depth-resolved information and builds:

• A-scans: depth profiles at a single point
• B-scans: cross-sectional slices formed by many A-scans
• Volumetric cubes: stacks of B-scans that enable thickness maps and 3D reconstructions

Technology families you may hear about (names and implementations vary by manufacturer):

• Time-domain OCT (older)
• Spectral-domain OCT (commonly used in ophthalmology)
• Swept-source OCT (often used for deeper penetration or faster acquisition, depending on design)

Some systems also provide OCT angiography (OCT-A), which estimates blood flow by detecting motion contrast between repeated scans. OCT-A is powerful but particularly sensitive to artifacts and requires careful clinical correlation.

How medical students encounter this device in training

Medical students and trainees typically meet Optical coherence tomography OCT scanner in:

• Ophthalmology rotations: interpreting macular scans and optic nerve/RNFL (retinal nerve fiber layer) outputs
• Diabetes and neurology teaching: understanding how structural imaging relates to visual symptoms and systemic disease
• Skills sessions: learning patient positioning, fixation coaching, and how poor technique can create misleading artifacts
• Case discussions and exams: recognizing classic patterns (with the caveat that OCT findings are rarely diagnostic in isolation)

A useful learning mindset is: OCT is a measurement tool and documentation tool, not a standalone diagnosis. The image is only as reliable as the acquisition quality, segmentation accuracy, and clinical context.

When should I use Optical coherence tomography OCT scanner (and when should I not)?

Appropriate use cases (general)

Local protocols vary, but Optical coherence tomography OCT scanner is commonly considered when clinicians need structural assessment or monitoring of:

• Macular conditions (edema, subretinal/intraretinal fluid patterns, tractional changes, atrophy patterns)
• Optic nerve and glaucoma-related assessment (RNFL and ganglion cell region analyses, with normative comparisons)
• Unexplained vision changes where retinal structural information may clarify differential diagnoses
• Pre-operative risk assessment (for example, detecting macular pathology before procedures where it could affect outcomes)
• Follow-up where quantitative comparisons over time are valuable (trend analysis, same device/scan protocol preferred)

In non-ophthalmic contexts, OCT may be used in specialty-specific ways (device form factor and workflow differ), so ensure you are referring to the correct system type and indications for your service.

Situations where it may not be suitable

Optical coherence tomography OCT scanner may be less useful or operationally challenging when:

• Media opacity limits signal (for example, dense cataract, significant corneal opacity, or vitreous hemorrhage), leading to low-quality scans
• The patient cannot cooperate with fixation or positioning (severe pain, inability to sit, extreme photophobia, certain pediatric scenarios without appropriate support)
• Immediate clinical action is required and OCT acquisition would delay time-critical care (workflow judgment required)
• The scan protocol does not match the clinical question (for example, performing only a macular scan when optic nerve assessment is needed)

Safety cautions and contraindications (general, non-prescriptive)

OCT is typically non-contact and does not involve ionizing radiation. However, safe use still requires attention to:

• Eye safety: light source class and exposure limits vary by manufacturer; follow IFU and facility policies
• Infection prevention: shared chin rests/forehead rests are high-touch surfaces
• Patient stability: elderly or unsteady patients can fall when moving to/from the device
• Photosensitivity and comfort: bright fixation targets or prolonged imaging can be uncomfortable for some patients

Contraindications are usually limited and model-dependent. If the system includes additional components (for example, contact lenses, add-on modules, or invasive accessories in other specialty implementations), contraindications and risks can change substantially.

Clinical judgment and supervision

For learners: image acquisition may be delegated, but ordering and interpretation should follow local scope-of-practice rules and supervision policies. For administrators: ensure governance clarifies who can acquire, who can interpret, and what happens when findings are uncertain or incidental.

What do I need before starting?

Required setup, environment, and accessories

A typical Optical coherence tomography OCT scanner setup requires:

• Stable power supply and appropriate electrical safety compliance for medical equipment
• A controlled environment (room lighting and space for patient seating and safe movement)
• A dedicated workstation and secure login process (user authentication and role-based access if available)
• Data connectivity for image storage and reporting (for example, DICOM—Digital Imaging and Communications in Medicine—or vendor-specific export formats; integration varies)
• Ergonomic patient supports (chin rest, forehead rest) and disposable barriers if used by your facility
• Lens cleaning materials approved for optics and surfaces (manufacturer compatibility matters)

Accessories and add-ons vary by manufacturer and model, and may include:

• Anterior segment adapters
• OCT-A modules
• External fixation aids
• Pediatric supports (in some settings)

Training and competency expectations

Competency for OCT scanning is often underestimated because the test looks simple. Minimum training elements usually include:

• Patient identification and data entry accuracy (prevent wrong-patient errors)
• Positioning and fixation coaching techniques
• Scan protocol selection (matching the clinical question)
• Recognizing poor image quality, motion artifacts, and segmentation errors
• Escalation pathways when findings are unexpected or images are unreliable
• Cleaning and infection prevention steps between patients

Facilities commonly use supervised sign-off for operators, periodic reassessment, and audit of image quality metrics (metrics vary by device).

Pre-use checks and documentation

A practical pre-use checklist (adapt to local policy and IFU) includes:

• Visual inspection of the device, cables, and patient supports for damage
• Cleanliness check of chin/forehead supports and any touchpoints
• Confirmation of calibration or self-test status (if the device provides it)
• Verification that software and scan protocols are correct for the clinic session
• Confirm data storage is available (avoid failed exports at end of clinic)
• Confirm correct patient demographics and laterality conventions in your workflow

Documentation expectations often include:

• Operator identity (or user login), date/time, scan protocol, and image quality indicators
• Any deviations from standard practice (poor cooperation, low signal due to media opacity)
• Incident or near-miss reporting if wrong-patient data entry or equipment malfunction occurs

Operational prerequisites: commissioning, maintenance readiness, consumables, and policies

Before going live, hospital operations teams typically coordinate:

• Acceptance testing and commissioning (biomedical engineering/clinical engineering validates functionality and electrical safety; IT validates connectivity and cybersecurity requirements)
• Preventive maintenance plan (intervals vary by manufacturer; include calibration checks, cleaning of optical pathways as permitted, and mechanical inspection)
• Service and support model (vendor service contract vs. in-house capability; spare parts availability varies by region)
• Software/firmware update governance (change control, validation, downtime planning)
• Consumables and cleaning supplies procurement (disposable barriers, wipes compatible with plastics/optics, printer supplies if printing is used)

Policies that prevent predictable failures include:

• Data retention and backup policy for imaging
• User access policy (who can edit demographics, who can delete studies)
• Downtime procedures (paper documentation, rescheduling rules, contingency imaging options)

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

Clear ownership reduces delays and blame-shifting:

• Clinicians: define clinical indications, required scan protocols, and reporting standards; provide oversight for interpretation
• Technicians/nurses/assistants/operators: acquire scans, ensure correct patient selection, document image quality issues, perform between-patient cleaning
• Biomedical/clinical engineering: commissioning, preventive maintenance, safety testing, failure triage, coordination with manufacturer service
• IT/informatics: network integration, cybersecurity, user authentication, storage, EMR integration, backup/archiving
• Procurement: contract terms, warranty, service level agreements, total cost of ownership, and vendor qualification
• Infection prevention team: cleaning/disinfection policy alignment with IFU and local risk assessment

How do I use it correctly (basic operation)?

Workflows vary by model, but the steps below are commonly universal for Optical coherence tomography OCT scanner in outpatient eye imaging.

Step-by-step workflow (typical)

1. Prepare the environment – Ensure the device is powered, the workstation is functioning, and the room is set up for safe patient movement.
2. Perform a quick equipment check – Confirm chin/forehead rests are clean, disposable barriers (if used) are in place, and optics appear free of smudges.
3. Log in and select the correct patient – Use your facility’s patient identification process. Avoid “workarounds” such as scanning under the wrong name to save time.
4. Choose the scan protocol – Select a protocol aligned with the clinical question (macula, optic nerve/RNFL, anterior segment, or angiography module if available).
5. Position the patient – Adjust chair height, chin rest, and forehead contact. Explain fixation and blinking expectations in simple language.
6. Align the scan – Center on the target region (for example, fovea for macular scans or optic disc for RNFL scans). Use the live image view to optimize alignment.
7. Optimize focus and signal – Adjust focus/refraction settings if available. Encourage stable fixation and brief pauses in blinking only as needed for capture.
8. Acquire the scan – Capture the planned scan set. Many systems provide an image quality indicator; use it, but don’t rely on it alone.
9. Review immediately – Check for motion, blink artifacts, decentration, shadowing, and segmentation errors. Repeat promptly if needed.
10. Save/export and document – Ensure studies are stored to the correct patient record and made available for clinical review (PACS, EMR, or vendor viewer—varies).
11. Between-patient cleaning – Clean/disinfect high-touch points per IFU and facility policy before the next patient.

Setup, calibration, and common universal concepts

Some systems require daily or periodic calibration checks; others handle this automatically. Regardless, universal “calibration thinking” includes:

• Confirming the system’s internal checks show normal status
• Ensuring the optical window is clean (smudges can mimic pathology or reduce signal)
• Maintaining consistent scan protocols for follow-up visits so comparisons are meaningful

Typical settings and what they generally mean

Terminology varies, but operators commonly adjust:

• Scan type/protocol: macular cube, line scan, optic disc/RNFL scan, anterior segment scan
• Scan density/resolution: more scan lines or higher density can improve detail but may take longer and be more sensitive to motion
• Averaging/repeat frames: averaging can reduce noise but increases acquisition time and motion sensitivity
• Focus/refraction compensation: helps sharpen images in patients with refractive error
• Fixation target selection: central vs. eccentric fixation aids in patients who cannot fixate centrally

A consistent operational rule: prioritize a scan that answers the clinical question reliably over chasing perfect aesthetics. A “pretty” scan that is decentered or incorrectly segmented can mislead.

Common operator tips (non-prescriptive)

• Coach fixation with short, clear instructions and confirm the patient understands what to look at.
• Watch for dry eye and excessive blinking; capture efficiently and allow normal blinking between scans.
• For serial monitoring, try to match the same protocol, eye alignment, and centering strategy each visit.
• Record when conditions reduce quality (poor cooperation, media opacity), so interpreters know the context.

How do I keep the patient safe?

Optical coherence tomography OCT scanner is usually non-contact and well tolerated, but patient safety is still an active process involving positioning, infection prevention, human factors, and escalation when something feels wrong.

Safety practices and monitoring during use

Key safety practices include:

• Correct patient and correct eye: use formal identification steps; confirm laterality in your workflow
• Safe positioning: ensure stable seating; assist patients with mobility limits; keep walkways clear
• Comfort and consent processes (as locally required): explain what the patient will experience (light, fixation target, short capture time)
• Minimize avoidable repeats: repeats increase patient fatigue and reduce throughput; repeat only when clinically or technically necessary
• Respect patient limits: stop if the patient becomes dizzy, distressed, or unable to continue safely

Optical and electrical safety considerations

General considerations (details vary by manufacturer):

• OCT uses a light source; safe use depends on compliance with the manufacturer’s intended use and applicable standards.
• Do not modify the device or use unapproved accessories; optical output and alignment can be affected.
• Maintain electrical safety checks as part of biomedical engineering programs (portable appliance testing or equivalent approaches vary by country).

“Alarms” and human factors

Many OCT systems do not have clinical alarms like monitors or ventilators, but they do present warnings and prompts such as:

• Low signal strength
• Fixation loss or motion warnings
• Alignment errors
• Storage/export failures

Human factors that reduce errors:

• Standardized scan naming conventions and protocols
• A “pause and verify” step before saving to prevent wrong-patient errors
• Clear escalation routes when operators are uncertain about image adequacy
• Adequate staffing so operators are not rushed into unsafe shortcuts

Risk controls, labeling checks, and incident reporting culture

Practical risk controls include:

• Checking labels and signs (laser/light safety labeling, if present; cleaning compatibility labels; service stickers)
• Locking down user permissions for deleting or editing studies, where feasible
• Reporting near-misses (wrong patient selected but caught before saving; repeated upload failures; unexpected shutdowns)
• Tracking quality issues (frequent segmentation errors may indicate software updates needed, protocol changes, or retraining)

A mature safety culture treats OCT errors like other medical equipment risks: predictable, preventable, and worth learning from.

How do I interpret the output?

Interpretation of OCT is a clinical skill that combines anatomy, pattern recognition, quality assessment, and correlation with symptoms and examination. The goal is not to “find something,” but to understand whether the output is reliable and what it means in context.

Types of outputs/readings

Depending on model and modules, Optical coherence tomography OCT scanner can produce:

• Cross-sectional B-scans: layered grayscale images showing tissue interfaces
• En face views: “top-down” reconstructions from volumetric data (availability varies)
• Thickness maps: color-coded maps of retinal thickness or specific layers
• Optic nerve head and RNFL analyses: circumpapillary thickness plots and sector maps
• Ganglion cell/inner plexiform layer analyses: often used in glaucoma assessment (terminology varies)
• Progression/trend reports: longitudinal comparison with prior scans (requires consistent acquisition and correct alignment)
• OCT-A outputs: flow or perfusion maps derived from repeated scans, plus vessel density metrics (metrics and validity vary)

How clinicians typically interpret OCT (a practical framework)

A useful stepwise approach:

1. Check identity and laterality – Confirm patient name/ID, date, and eye.
2. Assess scan quality – Look for motion lines, blink gaps, decentration, low signal, or shadowing.
3. Confirm correct anatomy and centering – A macular scan should be centered on the fovea; optic nerve scans should be centered on the disc with a valid circle placement.
4. Inspect segmentation – Automated layer boundaries can be wrong, especially with pathology or low signal. Segmentation errors can create false “thinning” or “thickening.”
5. Interpret structure – Identify fluid spaces, disruptions in reflective layers, tractional interfaces, or atrophic patterns, as relevant to the case.
6. Use quantitative outputs carefully – Thickness numbers and color codes depend on the device’s algorithm and normative database (which may not represent all populations equally).
7. Correlate clinically – Correlate with symptoms, visual acuity, slit-lamp/fundus findings, intraocular pressure, visual fields, or other imaging as appropriate.

Common pitfalls and limitations

OCT is powerful, but several limitations are common in real-world workflows:

• Artifacts mistaken for disease: motion, blink artifacts, poor focus, and shadowing can mimic pathology.
• Segmentation dependence: automated measurements can be wrong in the presence of edema, scarring, drusen-like changes, high myopia, or media opacity.
• Normative database limitations: “red/green” classification depends on device reference data and can misclassify individuals at the edges of normal variation.
• Inter-device comparability: thickness values and maps are not always comparable across manufacturers or even across software versions.
• OCT-A overinterpretation: flow artifacts, projection artifacts, and motion issues can create apparent nonperfusion or spurious vessels.

False positives/negatives and the need for correlation

OCT may miss disease when:

• The scan area does not include the lesion
• Poor signal reduces visibility of deeper structures
• Pathology is primarily functional rather than structural

OCT may overcall disease when:

• Segmentation fails
• Decentration alters thickness maps
• Normal anatomic variants are interpreted as abnormal

For trainees: make it routine to state whether the scan is interpretable and why. For administrators and quality leaders: consider auditing “repeat scan rates” and “uninterpretable scan reasons” to target training and throughput improvements.

What if something goes wrong?

Problems with Optical coherence tomography OCT scanner usually fall into four buckets: patient factors (cooperation/positioning), operator factors (protocol selection/technique), device factors (hardware/software), and workflow/IT factors (storage/ID errors). A structured approach reduces downtime and prevents unsafe improvisation.

Troubleshooting checklist (quick, practical)

• Confirm the correct patient is selected; stop if unsure.
• Check power and cables; ensure the device and workstation are fully powered.
• Restart the software application if it is frozen (follow local downtime rules).
• Inspect and clean optical surfaces only as permitted by IFU.
• Reposition the patient: chair height, chin rest, forehead contact, and head tilt.
• Re-coach fixation and blinking; reduce acquisition time if motion is a problem (protocol dependent).
• Verify scan protocol matches the clinical question (macula vs. disc).
• Check focus/refraction compensation settings if the image is blurred.
• Look for media opacity causes (for example, tear film issues, significant cataract); document limitations rather than forcing repeated scans.
• If segmentation looks wrong, review raw B-scans and consider reacquiring with better centering and signal.
• Confirm storage/network status; if images are not saving, follow local contingency documentation steps.
• Check for error messages and record them verbatim for biomedical engineering/vendor support.

When to stop use

Stop scanning and escalate according to local policy if:

• The patient becomes unwell, dizzy, or unsafe to continue (fall risk, distress)
• The device shows signs of electrical or mechanical hazard (smoke, burning smell, abnormal heat, exposed wiring)
• The system repeatedly mislabels, mismatches, or fails to save patient data (patient safety and data integrity risk)
• There is a suspected cybersecurity or unauthorized access issue

When to escalate to biomedical engineering or the manufacturer

Escalate when:

• Repeated hardware faults occur (motor/scan head errors, persistent calibration failure)
• Software updates or licensing issues prevent operation
• The device fails electrical safety checks or has intermittent power issues
• There is unexplained degradation in image quality across multiple patients (possible optics or alignment issue)
• The device is under warranty/service contract and requires authorized service to avoid voiding terms

Documentation and safety reporting expectations (general)

Good documentation shortens downtime and supports safety learning:

• Record date/time, device ID/asset number, user, error codes/messages, and what troubleshooting steps were attempted.
• Document any patient impact (delayed appointment, repeated imaging, distress) according to facility policy.
• Use incident reporting systems for wrong-patient near-misses, data loss events, and equipment hazards—even if no harm occurred.

Infection control and cleaning of Optical coherence tomography OCT scanner

Infection prevention for Optical coherence tomography OCT scanner is primarily about cleaning and disinfection of high-touch, patient-contact surfaces, while protecting sensitive optics and electronics.

Cleaning principles

• Follow the manufacturer IFU first; disinfectant compatibility varies by plastics, coatings, and adhesives.
• Use the correct contact time for your disinfectant (as defined by your facility policy and product label).
• Avoid excess liquid near seams, ports, and optics; spraying directly onto the device is often discouraged (exact guidance varies).
• Separate “dirty to clean” workflow: clean visibly soiled surfaces before applying disinfectant.

Disinfection vs. sterilization (general)

• Cleaning removes visible soil and reduces bioburden.
• Disinfection reduces microorganisms on surfaces; this is the usual requirement for external surfaces of OCT equipment.
• Sterilization is typically reserved for instruments entering sterile body sites; most OCT scanners are non-contact and do not require sterilization of the unit itself.

If your workflow involves any contact accessories (varies by model and specialty), reprocessing requirements can change; follow the IFU and your infection prevention team.

High-touch points to prioritize

Common high-touch areas include:

• Chin rest and chin cup surfaces
• Forehead rest and headband/strap (if present)
• Joystick and control knobs
• Keyboard, mouse, touchscreen, and patient response buttons
• Printer touchpoints (if used)
• Cable handles and commonly held edges of the device housing

Example cleaning workflow (non-brand-specific)

1. Perform hand hygiene and wear facility-approved gloves if indicated by policy.
2. Remove and discard disposable barriers (chin rest papers, forehead covers) if used.
3. If visible soil is present, clean with an approved wipe/cleaner first.
4. Apply facility-approved disinfectant wipes to high-touch areas, ensuring required wet contact time.
5. Allow surfaces to air dry; avoid wiping dry prematurely unless IFU allows.
6. Clean peripherals (keyboard/mouse/touchscreen) with compatible disinfectants.
7. Inspect for residue buildup that can affect moving parts or patient comfort.
8. Perform hand hygiene after glove removal.

Aligning IFU with facility policy

If your facility disinfectant conflicts with the IFU (causes cracking, clouding, or damage), escalate early. Procurement and infection prevention teams often need to select compatible products and standardize them across clinic rooms to avoid ad hoc substitutions that damage hospital equipment over time.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In everyday hospital purchasing, “manufacturer” often means the brand on the device and the company responsible for regulatory compliance, labeling, and IFU. An OEM (Original Equipment Manufacturer) is a company that makes components or subsystems that may be used inside another company’s branded product.

In imaging medical equipment, OEM relationships can involve:

• Optical components and scanning engines
• Cameras and sensors
• Mechanical stages
• Software modules or analytics components (licensing varies)

How OEM relationships impact quality, support, and service

OEM arrangements are not inherently good or bad, but they affect:

• Serviceability: parts availability and whether the branded manufacturer stocks components locally
• Update cycles: software and firmware updates may depend on third-party components
• Support boundaries: troubleshooting may involve multiple parties behind the scenes, affecting turnaround time
• Documentation: the end-user should rely on the branded manufacturer’s IFU and service documentation, regardless of who built subcomponents

Turkey

Turkey has a strong healthcare delivery network and a sizable private hospital sector, supporting demand for modern ophthalmic diagnostics. Import dependence exists for many high-end devices, but distributor and service networks are often well developed in larger cities. Procurement commonly emphasizes service response, training, and integration into high-throughput clinics.

Germany

Germany’s market is characterized by established ophthalmology services, structured clinical workflows, and high expectations for documentation and quality assurance. Facilities often evaluate interoperability, cybersecurity, and long-term service support as part of procurement. Access is generally strong, though smaller practices still weigh cost, space, and staffing considerations.

Thailand

Thailand’s demand is supported by a mix of public hospitals, private specialty centers, and medical tourism in some areas. OCT access is strongest in Bangkok and major cities, with variable availability elsewhere. Procurement frequently focuses on training, uptime, and vendor support models suitable for multi-site operations.

Key Takeaways and Practical Checklist for Optical coherence tomography OCT scanner

• Use Optical coherence tomography OCT scanner to answer a specific clinical question, not “just to scan.”
• Confirm the right patient and right eye before every acquisition and before saving.
• Match the scan protocol to the indication (macula, optic nerve/RNFL, anterior segment, or angiography where available).
• Treat scan quality assessment as the first step of interpretation, not an afterthought.
• Reacquire promptly if motion, blink artifact, or decentration makes the scan unreliable.
• Document reasons for poor quality (media opacity, poor fixation, discomfort) to guide interpretation.
• Expect automated segmentation to fail in pathology; always review the underlying B-scans.
• Avoid overreliance on color-coded “normal/abnormal” outputs; normative databases have limits.
• Use the same device and protocol for longitudinal follow-up whenever possible.
• Standardize naming conventions and scan sets across operators to reduce variability.
• Build operator competency programs with supervised sign-off and periodic quality audit.
• Plan commissioning with biomedical engineering, IT, and infection prevention from day one.
• Treat data integrity as a patient safety issue (wrong-patient studies are high-risk).
• Ensure secure logins and role-based access where available to protect image records.
• Validate storage, backup, and downtime workflows before high-volume clinics begin.
• Keep optics clean using only IFU-approved methods to avoid damaging coatings.
• Prioritize cleaning/disinfection of chin and forehead rests between patients every time.
• Use disinfectants that are compatible with plastics and adhesives used in the device.
• Avoid spraying liquids directly onto the unit unless IFU explicitly allows it.
• Track repeat-scan rates and root causes to improve throughput and patient experience.
• Escalate persistent image quality degradation across patients to biomedical engineering early.
• Capture and record error codes/messages verbatim to speed up service resolution.
• Stop use immediately if there are electrical safety concerns, smoke, or abnormal heat.
• Include service response time, parts availability, and software update terms in procurement.
• Budget for total cost of ownership (service contracts, updates, accessories, and training).
• Clarify who is authorized to interpret and who is authorized to acquire scans in policy.
• Use incident reporting for near-misses (wrong patient selected, unsaved studies), not only for harm.
• Design clinic rooms for safe patient flow to reduce falls and positioning injuries.
• Ensure accessibility plans for patients who cannot sit or fixate reliably (workflow alternatives).
• Educate trainees to state “interpretable vs. not interpretable” and justify their assessment.
• Correlate OCT findings with symptoms and examination; avoid single-test decision-making.
• Be cautious comparing thickness values across different manufacturers or software versions.
• For OCT-A, assume artifacts are common and confirm with structural scans and clinical context.
• Maintain a clear escalation pathway to the manufacturer for warranty and authorized repairs.
• Align cleaning, device IFU, and infection prevention policy to prevent damage and outbreaks.
• Include cybersecurity and network requirements in the initial purchase, not as an afterthought.
• Use consistent patient coaching scripts to improve cooperation and reduce retakes.
• Audit documentation completeness (protocol used, quality notes, operator ID) as part of QA.
• Keep a simple downtime plan for imaging and reporting when the system or network fails.
