Apparatus for reduced radiation computed tomography imaging

摘要

Methods and corresponding apparatus for imaging a portion of a patient's (22) body with a computed tomographic imaging system (10) configured to scan the patient's body at a cyclically varying view angle, in which the imaging system includes a radiation source (14) and detector array (18) providing a fan angle width of image data. In one embodiment, the method includes axially scanning (54) the portion of the patient's body, gating the radiation source on over less than a 360 DEG 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.
