摘要
A scanning tomography system has a gantry including a disk for supporting a X-ray source and detector array and rotatable about a central axis. Multiple scans are made to reduce the effects of motion artifacts and improve image quality. In addition, the detector array is supported by a suspension system and is movable about the focal spot of the X-ray source a small amount so that in one mode of operation the detector array can be shifted at a predetermined angle from one position to at least one other position during a scan so as to provide an increase in the number of unique X-ray paths so as to provide improved image quality. In a second mode of operation, the detector array can be offset from the center ray so as to provide a quarter of a detector offset.
