Abstract
Computerized tomographic imaging of the heart has great potential diagnostic value. The difficulty is that heart motion limits the data acquisition time to below 0.1 sec., but standard X-ray sources are not of sufficient intensity or mobility. A simple solution is proposed by using a rotating cathode filament with a fixed large stationary circular anode. In this design, X-ray detectors are placed on a concentric circle interior to the anode. To allow true planar X-ray projections, the detectors near the focal spot which would block the X-ray beam are moved synchronously out of the slice plane. An alternative method is also discussed where the detectors remain stationary and the nearer blocking detectors act as a filter for the X-ray beam.Keywords
