Patent ID: 7649974

Claim:
A method for controlling an X-ray imaging system that includes a gantry having a detector system and an X-ray source for radiating an X-ray beam along at least one of an imaging plane and a cone volume towards the detector system, said method comprising: controlling an X-ray source current between a first current level corresponding to a first radiation flux level and a second current level corresponding to a second radiation flux level; controlling the X-ray source high voltage between a first voltage level and a second voltage level based on a saturation level of the detector system; acquiring a plurality of subviews of patient attenuation data wherein a first set of subviews of patient attenuation data is acquired at the first radiation flux level and a second set of subviews of patient attenuation data is acquired at the second radiation flux level, the first radiation flux level being different than the second radiation flux level; and combining the first set of subviews of patient attenuation data and the second set of subviews of patient attenuation data to form corrected views for subsequent image generation.
