What is Optical coherence tomography OCT scanner: Uses, Safety, Operation, and top Manufacturers!

Introduction

Optical coherence tomography OCT scanner is a non-invasive imaging medical device that uses reflected light to create high-resolution, cross-sectional images of tissue microstructure. In everyday clinical practice, it is best known for eye care—helping clinicians visualize retinal layers, the optic nerve head, and other structures that are difficult to assess with standard examination alone. Variants of OCT technology are also used in other specialties (for example, intravascular imaging in cardiology), but the common theme is the same: fast, detailed structural imaging with minimal patient burden.

For hospital administrators, clinicians, biomedical engineers, and procurement teams, OCT sits at the intersection of clinical quality, operational throughput, and service sustainability. It is often a high-utilization piece of hospital equipment in ophthalmology clinics, diabetic eye screening programs, and specialty centers. It can also be a strategic investment for integrated care pathways where documentation, longitudinal monitoring, and image-sharing workflows are essential.

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

Optical coherence tomography OCT scanner is a diagnostic imaging clinical device that captures cross-sectional “slices” (and often 3D volumes) of tissue by measuring how near-infrared light reflects and interferes within different layers. You can think of it as an optical analogue to ultrasound imaging—using light instead of sound—designed to resolve fine structures at or near the micrometer scale. The exact wavelength, scanning engine, resolution, and performance characteristics vary by manufacturer and model.

Core purpose

At a high level, the purpose of an OCT scanner in healthcare is to:

Visualize tissue microstructure in vivo
Provide quantitative measurements (for example, thickness maps)
Create reproducible baseline documentation for follow-up comparisons
Support clinical decision-making and pathway monitoring when used alongside other assessments

Common clinical settings

Most commonly, this medical equipment is used in:

Ophthalmology outpatient clinics (retina, glaucoma, cornea, neuro-ophthalmology)
Screening and monitoring programs (for example, diabetes-related eye disease pathways)
Surgical planning and follow-up workflows (pre- and post-procedure documentation)
Specialized applications such as intraoperative OCT or catheter-based OCT in interventional settings (varies by manufacturer and configuration)

Key benefits for patient care and workflow

From an operations and quality perspective, the typical benefits include:

Non-invasive and fast acquisition: Many scans take seconds, which supports clinic throughput when protocols are well designed.
High-resolution structural detail: Useful for detecting subtle layer changes that may not be apparent on routine examination.
Standardized outputs: Many systems produce repeatable scan protocols and summary reports that improve longitudinal comparisons (when the same device, protocol, and software versions are used).
Digital documentation: Images and quantitative metrics can support multidisciplinary review, remote reading models, and audit-ready records when integrated into PACS/EMR via DICOM or vendor tools (capabilities vary by manufacturer).
Patient communication: Visual outputs can help clinicians explain findings in a structured way, improving engagement without changing the clinical message.

For procurement and biomedical engineering teams, these benefits must be weighed against total cost of ownership: service contracts, software upgrades, calibration tools, consumables (if any), cybersecurity patching, and downtime risk.

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

Appropriate use of Optical coherence tomography OCT scanner depends on specialty, workflow design, and clinician intent. The points below are general and operational; clinical appropriateness must be defined by your facility’s protocols, clinical leadership, and local standards of care.

Appropriate use cases (common examples)

An OCT scanner is commonly used when teams need:

Baseline structural documentation for future comparison (for example, initial assessment in a specialty clinic)
Monitoring over time, especially where small structural changes may matter clinically
Objective quantitative metrics (such as thickness maps or layer segmentation outputs) to complement clinical examination
Pre- and post-intervention imaging documentation as part of a standardized pathway (exact pathways vary by institution)
Triage support in high-volume services where imaging helps route patients to the appropriate clinic or urgency category (when governed by protocols)

In other specialties, OCT-derived imaging may be used in controlled settings (for example, catheter-based imaging in interventional cardiology). These applications have additional invasive and sterile-field considerations and should only be performed by trained teams following the specific IFU and facility governance.

Situations where it may not be suitable

There are practical limitations and scenarios where OCT imaging may be low-yield, unreliable, or operationally inappropriate, such as:

Patient cannot cooperate or maintain position (poor fixation, inability to sit/align, severe tremor, acute agitation)
Media opacity or signal-blocking conditions that prevent adequate light penetration (image quality may be poor; specifics vary by case)
Time-critical instability where moving the patient to imaging introduces unacceptable operational risk
Environments that cannot support safe operation (unstable power supply without protection, inadequate space, uncontrolled infection risks)
Where the scan output cannot be integrated or documented appropriately, creating traceability gaps (patient ID uncertainty, lack of storage, or workflow mismatch)

Safety cautions and contraindications (general, non-clinical)

OCT systems typically use low-power light and are designed to comply with applicable laser/light safety requirements (exact classification and conditions vary by manufacturer). Even so, safe use requires:

Follow the device’s labeling and laser/light safety classification and do not defeat interlocks or safety controls.
Avoid direct viewing into emission apertures and ensure staff follow local laser safety policies where applicable.
Use caution with vulnerable populations (for example, pediatrics or patients with limited ability to follow instructions), prioritizing comfort, short scan times, and trained operators.
For invasive OCT variants (for example, catheter-based systems), contraindications and risks are procedure-specific and must be taken from the IFU and clinical governance documents.

If there is uncertainty about suitability, the safe operational approach is to pause and seek guidance from the responsible clinician and/or the manufacturer’s clinical application support.

What do I need before starting?

Successful deployment of Optical coherence tomography OCT scanner depends on more than the console itself. Teams should plan for environment, accessories, competency, and documentation so imaging becomes reliable “infrastructure,” not a bottleneck.

Required setup and environment

Common practical requirements include:

Stable placement: A vibration-minimized surface or dedicated stand for tabletop systems; adequate clearance for patient chair positioning.
Power quality: Medical-grade outlets where required, surge protection, and—depending on site risk—UPS support for safe shutdown and data integrity.
Lighting control: Moderate room lighting can improve patient comfort; some scan types perform better with controlled ambient light (varies by manufacturer).
Network readiness: If exporting to PACS/EMR, plan IP addressing, DICOM configuration, user authentication, and cybersecurity controls.
Ergonomics and accessibility: Wheelchair access, adjustable seating, and operator posture considerations to reduce repetitive strain injuries in high-volume clinics.

Accessories and consumables (examples)

Exact accessories vary by manufacturer and model, but commonly include:

Patient interface items (chin rest papers, forehead rest covers, disposable shields)
Fixation targets or external displays (built-in or add-on, varies by system)
Lens cleaning supplies designed for optics (lint-free tissues, approved solutions)
Calibration/verification tools (phantoms or reference targets, if provided)
Export or printing capability (local printer, PDF reports, DICOM export tools)
For specialized OCT variants: sterile single-use components (for example, catheter-based systems) and procedure-specific consumables

Training and competency expectations

From a governance standpoint, organizations typically need:

Defined operator roles (technician, clinician, super-user, biomed support)
Initial training aligned to the IFU, local policies, and patient population
Competency assessment with periodic refreshers, especially when software upgrades change scan protocols or reporting
Clear escalation pathways for quality issues, suspected malfunction, and adverse event reporting

Pre-use checks and documentation

A consistent pre-use routine improves safety and reduces repeat scans:

Confirm the device passes internal self-tests and has no active fault indicators.
Inspect cables, connectors, moving parts, and patient contact points for damage or looseness.
Ensure optical windows/lenses are clean using approved methods only.
Verify user login, correct date/time, and patient ID workflow to prevent mislabeling.
Check storage capacity and network export status to avoid data loss.
Record quality control checks per facility policy (daily/weekly/monthly, varies by program).

How do I use it correctly (basic operation)?

Basic operation varies by manufacturer, scan type, and clinical specialty, but most Optical coherence tomography OCT scanner workflows follow a consistent pattern: prepare the system, identify the patient, align, acquire, review quality, and document/export.

Step-by-step workflow (general)

Power on and system readiness
Allow any required warm-up period and confirm the system completes self-checks. If the device prompts for calibration verification, follow the IFU.
User login and patient selection
Use authenticated user access where available. Create or select the patient record carefully to avoid laterality or identity errors, especially in high-throughput clinics.
Select the scan protocol
Choose a protocol matched to the clinical question and the service line (for example, macular volume, optic nerve head, anterior segment). Standardize protocols across operators to improve comparability.
Prepare the patient
Explain the procedure in simple terms, confirm comfort, and adjust chair height. Remove barriers that may interfere with imaging (for example, certain eyewear) as appropriate to your facility process.
Positioning and alignment
Use the chin and forehead rest (or handheld alignment techniques if applicable). Align the scanning beam to the target area using the live view. Many systems include alignment aids and focus indicators.
Optimize image quality
Adjust focus, polarization (if available), and sensitivity/exposure controls (terminology varies). Aim for stable fixation and minimal blinking during capture. Use eye-tracking or follow-up modes if supported.
Acquire the scan
Capture the selected scan pattern. Monitor on-screen quality metrics (often labeled signal strength, quality index, or similar—names and scales vary by manufacturer).
Review for artifacts and completeness
Immediately review for motion artifacts, blink interruptions, decentration, clipping, or segmentation failures. Repeat only if necessary and consistent with local practice.
Save, label, and export
Confirm laterality, scan type, and correct patient ID. Export to PACS/EMR or save to the device database per policy. Ensure compliance with data retention and privacy rules.
Post-use cleaning and reset
Clean high-touch and patient-contact surfaces according to infection control guidance and reset the room for the next patient.

Calibration and quality assurance (high-level)

Some systems perform automatic internal calibration at startup; others require periodic verification.
Facilities often implement phantom checks or standardized test scans to track drift and image consistency over time (methods vary by manufacturer and program).
Any changes in software version, segmentation algorithms, or normative databases can affect reports; document these changes for longitudinal comparability.

Typical settings and what they generally mean

Naming and availability vary by manufacturer, but common OCT settings include:

Scan pattern: line scan, raster/cube volume, radial scans, or widefield mosaics.
Scan area and density: larger areas cover more anatomy but can trade off speed or sampling density; denser scans can improve detail but may be more motion-sensitive.
Averaging / frame accumulation: combining repeated frames can reduce noise but increases acquisition time and motion sensitivity.
Focus / Z-offset: optimizes the focal plane and depth placement to improve layer visibility.
Eye tracking / follow-up registration: aligns repeat scans to prior locations for better comparisons (availability varies by manufacturer).
OCT angiography mode (if present): uses repeated scans to estimate flow-related signal changes; more sensitive to motion and segmentation choices (varies by manufacturer).

For non-ophthalmic applications (for example, catheter-based OCT), operation includes additional steps such as sterile setup, device priming, and acquisition synchronized with procedural workflow. Those details are highly system-specific and must be taken from the IFU and procedural protocols.

How do I keep the patient safe?

Patient safety with Optical coherence tomography OCT scanner is largely driven by correct identification, comfortable positioning, infection control, and adherence to manufacturer safety controls. While OCT imaging is generally non-invasive for ophthalmic use, high-volume workflows can create preventable risks if processes are inconsistent.

Practical safety practices

Confirm patient identity and laterality using your facility’s standard (two identifiers, wristband/registration checks where applicable).
Explain the sensations and expectations (bright fixation light, need to hold still briefly) to reduce sudden movement and anxiety.
Position for comfort and stability: adjust chair height, chin rest position, and operator ergonomics to avoid patient strain and falls when standing up.
Minimize contact pressure: ensure the patient does not press excessively into the chin/forehead rest, which can cause discomfort and movement.
Respect accessibility needs: have a safe approach for wheelchair users and patients with limited mobility.

Light/laser safety and facility controls

Follow the device labeling for laser/light classification and safe operating conditions (varies by manufacturer).
Do not override interlocks or operate the system with damaged housings, missing covers, or modified optics.
Implement local policies for laser safety where required (signage, staff training, controlled access), even if the system is designed for low-risk classification in normal use.

Monitoring during acquisition

OCT systems often display warnings that are quality-related rather than life-safety alarms. Even so:

Respond to on-screen prompts about low signal, saturation, motion, or alignment by pausing and correcting setup.
Watch the patient, not just the screen: dizziness, discomfort, tearing, or inability to maintain posture are practical reasons to stop and reset.
Avoid repeated unnecessary scans: repeat acquisition increases patient burden and operational delays; prioritize getting it right the first time.

Human factors and error-proofing

Standardize protocols (scan names, laterality checks, minimum quality thresholds) to reduce variability between operators.
Use role-based access and audit trails where possible to support accountability.
Maintain a clear room layout to reduce trip hazards from cables, foot pedals, and shared workstations.

How do I interpret the output?

Interpretation of OCT outputs is a clinical activity that must be done by trained professionals within the context of the patient’s history, examination, and other investigations. This section describes how outputs are typically structured and common pitfalls that affect reliability.

Types of outputs/readings you may see

Depending on configuration, an Optical coherence tomography OCT scanner may generate:

B-scans (cross-sectional slices) showing layered tissue structure
A-scan profiles (the underlying depth reflectivity signal; often not shown directly in routine reports)
En face views (top-down representations reconstructed from volumetric scans)
3D volumes that can be scrolled through slice-by-slice
Thickness maps and sector plots derived from segmentation of anatomical boundaries
Deviation/normative comparisons (color-coded probability maps; dependent on database and software version)
OCT angiography-style flow maps if the system supports it (methodology varies by manufacturer)
Longitudinal trend reports comparing multiple visits (reliability depends on consistent protocol and registration)

How clinicians typically approach review (general)

A structured review often includes:

Start with image quality: confirm signal strength/quality index is acceptable and that the scan is centered and complete.
Look for artifacts before drawing conclusions (motion, blink, shadowing, mirror artifacts, saturation).
Correlate structure with maps: verify that thickness changes match the underlying B-scan anatomy rather than a segmentation error.
Compare like-for-like over time: same device, same scan protocol, and ideally the same software version; changes in algorithms can alter measurements.
Document limitations when quality is compromised, rather than forcing quantitative interpretation.

Common pitfalls and limitations

Operational and technical limitations often explain “unexpected” outputs:

Segmentation errors: automated boundary detection can fail, especially in distorted anatomy or low-quality scans; this can falsely inflate or reduce thickness values.
Device-to-device variability: measurements and color scales can differ between manufacturers and even between software versions.
Normative database mismatch: “normal/abnormal” flags depend on demographics and inclusion criteria that may not match your population; details may be limited or not publicly stated.
Media opacity and shadowing: structures behind opacities may be obscured, limiting interpretation.
Over-reliance on summary reports: a single “green/red” indicator should never replace careful review of the underlying slices.

For procurement teams, these limitations matter because they influence training needs, reading workflows, and the importance of consistent fleet standardization.

What if something goes wrong?

Even well-run imaging services will face occasional failures: poor image quality, software glitches, network issues, or hardware faults. A predefined troubleshooting and escalation plan reduces downtime and prevents unsafe workarounds.

Troubleshooting checklist (practical)

No power / won’t start
Confirm mains power, outlet status, breakers, and any UPS state; inspect power cable integrity and secure connections.
System starts but imaging fails
Check whether the device reports a specific error code; restart only if permitted by policy and IFU; verify the scan head/cables are properly seated.
Poor image quality or low signal
Clean optical surfaces using approved methods; re-check alignment and focus; reduce motion by improving patient positioning; confirm scan protocol and eye tracking settings.
Motion or blink artifacts
Coach the patient, shorten acquisition time (if protocol allows), and consider repeating only the minimum necessary scan.
Segmentation/report looks incorrect
Review raw B-scans first; confirm correct laterality and scan centering; consider whether software updates changed analysis behavior.
Cannot export to PACS/EMR
Verify network connectivity, DICOM configuration, credentials, and storage availability; document the incident to prevent data loss.
Software freezes or crashes
Save what you can, follow controlled restart procedures, and report to IT/biomed with timestamps and steps leading to the issue.

When to stop use immediately

Stop using the medical device and secure it for assessment if you observe:

Burning smell, smoke, overheating, or unusual electrical noise
Visible damage to housings, optics, cables, or patient-contact hardware
Repeated safety-related error messages that do not clear per IFU
Any patient adverse event or near-miss linked to the device workflow
Evidence of fluid ingress or contamination in areas not designed to be cleaned

When to escalate to biomedical engineering or the manufacturer

Escalate promptly when:

The device fails self-tests or calibration verification repeatedly
Faults recur after basic checks and controlled restart
There is suspected cybersecurity compromise or unauthorized software behavior
Replacement parts, optical alignment, or internal servicing may be required
You need official guidance on cleaning agent compatibility or accessory validation

Capture logs, screenshots, and error codes where possible, and document actions in the equipment service record. Avoid informal modifications or “temporary fixes” that bypass safety controls.

Infection control and cleaning of Optical coherence tomography OCT scanner

Infection prevention for Optical coherence tomography OCT scanner is usually about consistent cleaning of non-critical surfaces (contact with intact skin) and high-touch operator interfaces. Some configurations and accessories may introduce higher-risk contact points; always follow your facility policy and the manufacturer’s IFU for approved agents and methods.

Cleaning principles for OCT in routine clinical use

Treat the OCT unit as shared hospital equipment with frequent patient turnover.
Prioritize between-patient cleaning of any patient-contact surfaces and frequent disinfection of high-touch operator surfaces.
Use only manufacturer-approved disinfectants for plastics, coatings, and optical components; chemical compatibility varies by manufacturer.
Avoid overspray, dripping, or pooling liquids near vents, seams, connectors, and optics.

Disinfection vs. sterilization (general)

Cleaning removes visible soil and reduces bioburden.
Disinfection uses chemicals to reduce microorganisms to an acceptable level for non-critical items; the level (low/intermediate/high) depends on risk assessment and policy.
Sterilization is typically not applicable to the OCT console itself, but may apply to certain accessories in specialized settings.
For invasive OCT variants (for example, catheter-based systems), sterile single-use components and sterile technique requirements come from the specific product IFU.

High-touch points to include in your routine

Common areas that require consistent attention:

Chin rest and forehead rest surfaces
Patient handles or stabilizing bars
Joystick and control knobs
Keyboard, mouse, touchscreen, and buttons
External fixation target housing (if patient-facing)
Cable surfaces that are frequently handled
Patient chair controls if integrated into the imaging station

Example cleaning workflow (non-brand-specific)

Perform hand hygiene and don appropriate gloves per policy.
Remove and discard disposable chin rest papers/covers.
If required, power the system to a safe state (standby/off) before cleaning; follow IFU to avoid data loss.
Use a facility-approved disinfectant wipe (agent and concentration per policy and IFU). Do not spray directly onto the device.
Wipe patient-contact surfaces first (chin/forehead rest), then operator high-touch surfaces (joystick, keypad, touchscreen).
Maintain the disinfectant wet contact time specified on the disinfectant label and allowed by the device IFU.
Allow surfaces to air dry or wipe dry if the IFU permits.
For optical windows/lenses, use only approved lens cleaning materials and techniques to prevent scratching or coating damage.
Inspect for residue, streaking, cracks, or loosening of patient interface components.
Document cleaning if required by your infection control program (for example, in high-risk clinics or audits).

Consistency matters more than complexity. A simple, standardized between-patient routine—supported by readily available supplies and clear responsibility—typically delivers better outcomes than a complex protocol that staff cannot sustain.

Medical Device Companies & OEMs

In the context of Optical coherence tomography OCT scanner, the “manufacturer” is the company legally responsible for the finished medical device placed on the market under its name. An OEM (Original Equipment Manufacturer) may produce complete systems or key subsystems (optical engines, light sources, scanning components, detectors, software modules) that are integrated into a branded product. Some companies are both: they manufacture under their own brand and also supply OEM components to others (arrangements vary and are not always publicly stated).

Why OEM relationships matter to hospitals

OEM relationships can affect:

Quality management and traceability: who controls design changes, software updates, and risk management documentation.
Service and spare parts availability: whether parts are stocked locally, lead times, and whether third-party servicing is permitted.
Software lifecycle and cybersecurity: how long operating systems are supported, patch cadence, and vulnerability response processes.
Regulatory documentation: clarity of IFU, cleaning validation, and accessory compatibility.
Clinical performance consistency: component substitutions and algorithm updates can change measurement outputs.
