ABSTRACT:
An x-ray CT system acquires scout data over a region of a patient prior to performing a scan. The scout data is employed to locate the patient in a succession of slices over the region. Geometric scan parameters including display field of view (DFOV), scan field of view (SFOV) and patient centering offsets (X.sub.OFF,Y.sub.OFF) are calculated from the scout data, displayed to the operator, and used as default values in the subsequent scan of the region.
