Abstract
An improved X-ray tomography system includes means for providing error information at each incremental angular position of the 360.degree. rotation of each scan, indicative of any mechanical lateral movements of the various tomography components during a scan, and means for compensating the data derived from the analog information signals representative of X-ray flux detected by the detectors during each projection view as a function of the error information during the back projection process so as to provide accurate scan data.
