Abstract
The present invention, in one form, is an imaging system which synchronizes the emission of x-rays and the collection of data to a heart cycle to provide improved image quality. In one embodiment, the imaging system utilizes a synchronization unit to determine a selected heart period and to control generation of x-ray beams during the selected period. As the x-ray beams are emitted toward a detector, data is collected for a view angle. As the heart continues to cycle, data for a series of view angles is collected so that an image of the heart during the selected period is generated.
