HIGH RESOLUTION COMPUTED TOMOGRAPHY USING EDGE-ON DETECTORS WITH TEMPORALLY OFFSET DEPTH-SEGMENTS USING EDGE-ON DETECTORS WITH TIME-

摘要

A measurement method performed by a computed tomography (CT) system 10 is disclosed. The CT system 10 includes an x-ray detector array consisting of an x-ray source and a photon count edge-on detector, each edge-on detector having a plurality of depth compartments Quot;) / RTI The method provides a time offset between measurement periods of at least two different detection elements (15) arranged at different depths, the time offset being selected such that at least two measurement periods are at least partially overlapped in time . The control unit 10 for the CT system and the measuring circuit 30 for the CT system 10 are also disclosed. A computer program for the CT system 10 is also disclosed. The present invention provides a higher sampling frequency in the angular direction.
