A system for reconstruction of computed tomography (CT) images in a video frame time (1/30 sec) is described. The system implements the filtered backprojection algorithm using an electrooptic filtering technique, an optical backprojection, and a video detector. When coupled to a real-time system for acquiring projection data, the combined system realizes what we term CT videography.
