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.
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.
Reduced source spacing for multi-source, multi-detector X-ray imaging systems is provided by allowing channels within an X-ray collimator to intersect within the body of the collimator.
