Abstract
An apparatus and method for controlling movement of a plurality of fixed detectors arranged in a computed tomography (CT) system that includes a rotating X-ray source. The method including obtaining a view angle of the X-ray source, determining a tilt angle for a detector of the plurality of detectors that is within a scan field-of-view of the X-ray source at the obtained view angle so that an outer face of the detector directly faces the X-ray source, and causing the detector to be moved to the determined tilt angle.
