IMAGE-DATA ACQUIRING DEVICE OF TWO-HEAD DETECTOR WHICH CAN BE ADJUSTED

摘要

PURPOSE: To shorten an imaging time necessary for forming the image of a 180 deg. single photon emitting computer tomographic equipment by regulating angular displacement to a specific size between first and second detectors and keeping an image direction within a plane. CONSTITUTION: The positions of first and second detectors 4 are set so that the relative angle of them is 90 deg. and the image directions 2 of the detectors are set so as to form 90 deg. and an imaging time of 180 deg. scanning is reduced to 1/2 the imaging time of a single head apparatus because data are obtained from two stop points at the same time. An operator can move the detectors 4 to regulate desired relative angular displacement. Operation is repeated until data are obtained with respect to all necessary angle stops and the position data stored in a microprocessor is used to form an image from the obtained data. By this constitution, an apparatus achieving the shortening of an imaging time and capable of being rotated to a desired angle position and high in adaptability can be realized.
