Stanford researchers have developed a system and method to increase sampling in x-ray and CT images by deflecting the focal spot of an x-ray tube. This invention achieves focal spot z-wobble by shaping the rotating anode.
Disclosed are embodiments of methods for reconstructing x-ray projection data (e.g., one or more sinograms) acquired using a multi-source, inverse-geometry computed tomography ("IGCT") scanner.
A CT imaging system includes a rotatable gantry having an opening to receive an object to be scanned having a small field-of-view (FOV) inside a large FOV.
