1. An imaging system, comprising: a rotating gantry that rotates around an examination region; a radiation source that emits radiation that traverses the examination region, wherein the radiation source is affixed to and rotates with the rotating gantry; a controller that activates the radiation source to emit radiation and deactivates the radiation source to stop radiation emission, wherein the controller activates the radiation source to continuously emit radiation at pre-determined angles as the rotating gantry and the radiation source rotate around the examination region; a detector array, located across from the radiation source opposite the examination region, that detects radiation that traverses the examination region at the predetermined angles as the rotating gantry and the radiation source rotate around the examination region and generates a signal indicative thereof; and a reconstructor that reconstructs a sub-portion of the signal corresponding to a single one of the pre-determined angles to generate a radiographic image corresponding to the single one of the pre-determined angles.
