DUAL X-RAY TUBE GATING

摘要

A computed tomography system includes at least a first x-ray source (14) that continuously emits radiation through an imaging region (22) while rotating about the imaging region (22) during a data acquisition cycle and at least a second x-ray source (14) that periodically emits radiation through the imaging region (22) while rotating about the imaging region (22) during the data acquisition cycle. A first set of detectors (24) detects projection radiation corresponding to the at least first x-ray source (14) and generates first projection data indicative of the detected radiation, and a second set of detectors (24) detects projection radiation corresponding to the at least second x-ray source (14) and generates second projection data indicative of the detected radiation.
