Medical Image Quality Testing Services

Overview

Medical Image Quality Testing Services | Cameras have become a core component of modern medical devices. Endoscopes guide minimally invasive procedures, surgical microscopes and operating cameras support the surgeon, and digital pathology scanners turn glass slides into images that pathologists diagnose from. In each case, what the physician sees on the display is the result of a complete imaging chain and the quality of that image can directly affect a diagnosis or the outcome of a procedure. For this reason, image quality in medical imaging is not a cosmetic property but a performance characteristic. Resolution, contrast, color fidelity, noise, dynamic range, distortion, and field of view all determine how reliably a device represents the tissue or structure it is pointed at. Regulatory pathways — the FDA 510(k), De Novo, and PMA processes in the United States, or the EU Medical Device Regulation (MDR) in Europe — require that imaging performance is characterized and documented, but they generally do not prescribe how each optical attribute should be measured. That is where the iQ-Lab comes in: objective, reproducible measurements, traceable to recognized methods and standards.

Let the iQ-Lab characterize your imaging device

Our iQ-Lab is one of the world's largest independent camera test labs. We characterize the optical image quality of endoscopes, surgical cameras, and digital pathology systems under controlled, reproducible conditions — using methods aligned with the ISO 8600 series and the photographic image quality standards that medical imaging has adopted.
Most of our work in this field supports the preliminary investigations that precede formal qualification. In several projects, our measurement data has gone further and fed directly into our clients' qualification and change-approval documentation — because results that are objective, reproducible, and traceable can stand as evidence within a manufacturer's own submission.

What we Test

Resolution & Sharpness (SFR)

Spatial frequency response and MTF (incl. MTF10 at the best focus point), measured against ISO 12233-compliant targets — how clearly fine tissue structures are rendered.

Learn more

Dynamic Range & OECF

Opto-electronic conversion function and dynamic range in f-stops, characterizing how the device handles bright highlights and deep shadows in a single scene.

Learn more

Noise & SNR

Signal-to-noise ratio, including temporal and fixed-pattern noise — decisive for low-light imaging, where many medical devices operate.

Learn more

Color & White Balance

Color accuracy and white-balance deviation under reproducible, device-specific illumination — central for both endoscopy and digital pathology.

Learn more

Field of View & Distortion

Field of view, direction of view, geometric distortion, and chromatic aberration — including the wide-angle optics typical of endoscopes.

Learn more

Light Leakage & Stray Light

Verification that the imaging system does not introduce unwanted light or veiling glare that would obscure the scene under clinical conditions.

Learn more

Relevant Standards & Frameworks

The standards our methods follow, and the frameworks that govern market access

ISO 8600 Series

The dedicated standard series for endoscopes. ISO 8600-1 covers general requirements and terms, ISO 8600-3 defines field of view and direction of view, and ISO 8600-5 specifies the optical resolution of rigid endoscopes.

ISO 12233 / 15739 / 14524

Photographic image quality standards adopted in medical imaging: methods for resolution and SFR (ISO 12233), noise (ISO 15739), and the opto-electronic conversion function / OECF, from which dynamic range is derived (ISO 14524).

Publisher page

FDA (United States)

Medical imaging devices reach the US market through the FDA 510(k), De Novo, or PMA pathways, which require documented imaging performance. FDA guidance on digital pathology (WSI) devices makes color performance a required system test.

Publisher page

EU MDR (Europe)

The Medical Device Regulation (EU) 2017/745 governs market access, with conformity assessed by notified bodies for CE marking. It requires that a device's performance — including imaging performance — is characterised and documented.

Prefer to Test In-House?

If you run your own lab, we supply the same charts, light sources, and software the iQ-Lab uses.

iQ-Analyzer-X

Our analysis software for evaluating resolution, distortion, color, noise, and dynamic range from a single capture — turning each measurement into a reproducible result.

Learn more

camSPECS & TE Color Charts

Spectral camera characterization and reference color charts for precise, repeatable color measurement — central to digital pathology and endoscopy.

Learn more

iQ-LED & LE7

LED light sources that reproduce custom spectra with high uniformity, so a device can be tested under illumination matched to its intended use.
