Abstract:
A method for generating an image of an object in a computed tomography (CT) system, the CT system including an x-ray tube for emitting x-ray beams and a detector array, the detector array including a plurality of detectors aligned with the x-ray tube for receiving the x-ray beams, said method comprising the steps of:determining a cycle of a heart;generating at least one image view data of the object for at least one selected portion of the heart cycle; andgenerating at least one image of the object based on the image view data;wherein the object is a portion of the circulation system other than the heart, and wherein generating image view data of the object for at least one selected portion of the heart cycle comprises the step of gating an x-ray on signal so that an anode-cathode voltage of the x-ray tube is cycled on for the selected portion of the heart cycle and cycled off after a defined period of time.
