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.

• 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.
