Luminance is the brightness of color which incorporates the hue and saturation of colors. Within the scope of ultrasound, luminance suppresses white noise and automatically optimizes gain levels. This rendering and lighting technique can be used to examine anatomical structures by applying color and illumination to enhance features. Luminance not only minimizes misinterpretation by dramatically improving accuracy with visualization and identification of structures and borders but aids ultrasound imagery in setting the shadow and highlight point of the focal area which in turn creates a more detailed image.

Although luminance is useful in a variety of specialties, it has been especially popular and valuable in rendering 3D/4D realistic images of fetus features and structures in utero. The color and illumination elements which luminance provides allows for a more precise diagnosis within the realms of morphologies, malformations, and bone shape abnormalities in developing fetus’. In 2D imaging the brightness of tones in ultrasound helps by setting the shadow and highlight points of the image. By increasing the extracted changes in luminance with aperture, it builds a more detailed image with a smaller transducer than what was physically capable before. With these enhanced capabilities, technicians can assist with greater precision and accuracy during biopsies leading to a more effective diagnose.
