ABSTRACT:
A computed tomography system includes at least two x-ray sources (108), a at least one common detector (124), and a reconstruction system (136). The at least two x-ray sources (108) are aligned at different z-axis locations at about a same angular position and concurrently emit radiation that traverses an imaging region (116). The at least one detector (124) detects radiation emitted by the at least two x-ray source (108) and generates composite data indicative of the detected radiation. The reconstruction system (136) reconstructs the composite data to generate one or more images.
