Abstract:
1. A volumetric stationary CT system comprising: at least one stationary detector extending generally around at least a portion of an imaging volume; at least one stationary distributed X-ray source placed proximal to the at least one stationary detector; and a source controller for triggering one or more emitters in the at least one stationary distributed X-ray source for acquiring volumetric data by the at least one stationary detector, wherein the at least one stationary detector and the at least one stationary distributed X-ray source are configured to cooperate to contribute towards mathematical completeness of acquired volumetric data for image reconstruction, and wherein the at least one stationary distributed X-ray source includes at least two full ring sources, wherein the at least one stationary detector includes a pair of ring detectors and wherein at least one ring source of the at least two full ring sources is positioned between the pair of ring detectors.
