An image processing system for providing original images for synthesizing multiplex holograms is developed. This system reconstructs 3D surface rendering images of internal organs and/or bones of a patient from a series of tomograms such as computed tomography. Image processing includes interpolation, enhancement, extraction of diseased parts, selection of axis of projection, and compensation of distortions. This paper presents the features of this system, along with problems and resolutions encountered in actual test operation at hospitals.
