Abstract:
1. A method for adaptively acquiring computed tomography scan data, comprising: acquiring heart cycle data for a patient undergoing imaging; rotating an X-ray source about the patient; activating the X-ray source during two or more heartbeats identified in the heart cycle data, wherein the X-ray source, when activated, emits an X-ray beam that generates projection data for an imaged volume about which the X-ray source is rotating, and wherein one or more of the activations of the X-ray source are adapted in terms of one or more of timing, duration or operating current based on data completeness; combining the projection data acquired during the two or more heartbeats based on one or more consistency-based criteria to generate a substantially complete set of projection data; and reconstructing the substantially complete set of projection data to generate one or more volumetric images at a cardiac phase of interest.
