Title: Methods and apparatus for reduced radiation coronary computed tomography imaging

Abstract: Methods and corresponding apparatus for imaging a portion of a patient's body with a computed tomographic imaging system configured to scan the patient's body at a cyclically varying view angle, in which the imaging system includes a radiation source and detector array providing a fan angle width of image data. In one embodiment, the method includes axially scanning the portion of the patient's body, gating the radiation source on over less than a 360 .degree.view angle cycle of the axial scan, acquiring image data of the portion of the patient's body during at least a portion of the time the radiation source is gated on, and assembling the acquired image data into an image of the portion of the patient's body.
