Abstract
The present invention discloses a computed tomography imager comprising: an x-ray source disposed in a gantry; a detector assembly for receiving an x-ray emission from an x-ray source, the x-ray source and the detector assembly rotatable about an imaging target; an imager control system for selectively modulating a kVp operating value in the x-ray source during a scan slice in accordance with an x-ray modulation software program; and a computer for receiving data from the detector assembly, and for providing control signals to the imager control system by executing the x-ray modulation software program for at least a portion of the total possible rotational scanning range of the x-ray source.
