Patent number: 7313213Abstract: A CT imaging system has a rotatable gantry, a table movable fore and aft through an opening defined within the rotatable gantry, and a controller that incrementally moves a subject disposed on the table through a number of discrete data acquisition positions for the acquisition of physiologically gated CT data.
