Abstract :
Hands, arms, and legs immersed in a water bath can be imaged by the complementary methods of reflection and transmission mode. The two system configurations and their related image processing are described. The reflection system collects B-scans from many directions and generates geometrical cross sections as well as spatial distributions of physical parameter in the insonified tissue by applying computer tomographic principles. Regions of interest can be investigated interactively with reduced resolution. Planes perpendicular to the cross section are imaged by the transmission system. Its key element is a large, electronically scanned matrix of receivers. Because of its fast video frame rate, the function of tendons and joints can be inspected during natural movements.<>
