A new concurrent processing system for medical stereo radiographs

A new stereo processing system for medical X-ray imaging, based on the principle of stereo imaging and display, is presented. The whole system consists of three subsystems: (1) the X-ray control unit, (2) the image acquisition and processing subsystem, and (3) the stereo display subsystem. The parallel structure with two channels for X-ray image processing, the digital substraction angiography technique, and the stereo depth determination technique with the interaction mode are described. The architecture of the system and the improved reconstructed stereographic X-ray image display system are introduced. The merits of the system and applications are discussed.
