    Medical & Endoscopic

    Industry Overview

    One of the most critical aspects of our lives is our health. We rely on doctors and other medical professionals when we are sick or injured, placing great trust in them to make the right decisions about our health. As a result, health professionals need access to the best technology to help them make informed decisions. One area of technology that remains vital is the proper functioning of endoscopic camera systems. These cameras rely on high image quality to deliver clear images to doctors of what is happening inside their patients.

    Image quality is a critical factor in medical imaging and endoscopic procedures. The ability to produce precise, accurate, and detailed images can directly impact diagnostic accuracy and procedural decisions. These challenges make evaluating and maintaining image quality a top priority for manufacturers of medical and endoscopic cameras. Additionally, nearly all medical and endoscopic camera systems must meet stringent regulatory and performance standards to ensure patient safety and optimal outcomes.

    Evaluating camera performance requires understanding the factors that define image quality and the test tools available to assess them. We offer a wide range of solutions, from test charts to illumination devices, to help endoscopic manufacturers assess the image quality performance of their products.

    Main Applications

    There are a few primary applications that are crucial to determining the functionality of endoscopic camera systems.

    Camera Resolution

    Camera Resolution

    Without high-resolution images, crucial objects/artifacts may appear blurry or be misidentified, leading health care officials to draw false conclusions.
    Optical Distortion

    Optical Distortion

    Endoscopic cameras typically have a wide field of view and could encounter distortion challenges. Understanding the effects of distortion is crucial for image quality.
    Color Calibration

    Color Calibration

    Endoscopic cameras need to be color-calibrated appropriately to ensure that objects are depicted correctly in a scene.
    Signal-to-Noise Ratio (SNR)

    Signal-to-Noise Ratio (SNR)

    Signal-to-Noise Ratio (SNR) indicates the clarity of an image relative to background noise. Unwanted noise in an image can lead to poor resolution and texture loss.

    Relevant Standards for Medical Imaging

    A look at the image quality standards that are essential to understand when evaluating endoscopic cameras

    ISO 12233 – Resolution

    Outlines the metrics and test methods for measuring the resolution and SFR performance of a camera system.

    ISO 15739 – Noise

    Outlines the metrics and test methods for determining the SNR and dynamic range performance of a camera system.

    ISO 17850 – Distortion

    Outlines the metrics and test methods for evaluating the geometric distortion performance of a camera system.

    A look at example solutions for building a full image quality test setup for medical and endoscopic camera systems.
    Image quality testing of endoscopic camera testing

    Test Setup 1: Endoscopic with CAL4

    The goal of this solution is to evaluate the essential image quality factors relevant to endoscopic camera performance. Factors include resolution, dynamic range, contrast differentiation, color accuracy, noise, and optical distortion.

    Ideal equipment:

    • TE253 9x – Resolution test chart

    • TE188 – ColorChecker

    • CAL4 – Test chart illumination

    • iQ-Analyzer-X – Analysis software

    This solution is built around the CAL4, a 0,3m integrating sphere that provides uniform illumination over the 50 mm chart plane. The test charts are available in our smallest size of D35 (50 x 50 mm), and the iQ-Analyzer-X can evaluate the test results.

    Test Setup 2: Endoscopic with iQ-FoV Box XS*

    Test Setup 2: Endoscopic with iQ-FoV Box XS*

    The goal of this solution is to evaluate the essential image quality factors relevant to endoscopic camera performance. Factors include resolution, dynamic range, contrast differentiation, color accuracy, noise, and optical distortion.

    Ideal equipment:

    • iQ-Fov Box XS* – Resolution measurements

    • TE283 – Slanted edge test chart

    • Universal Camera Mount – Camera Alignment

    • iQ-Analyzer-X – Analysis software

    This setup is built around the iQ-FoV Box XS. It is optimized for resolution measurements across wide fields of view, such as those in endoscopic cameras. The compatible test chart is the TE283 slanted-edge chart (50 x 50 mm), and the iQ-Analyzer-X can evaluate the test results.

    *The iQ-FoV Box XS is currently under development.
