Patent ID: 7526062

Claim:
A method, comprising: generating a radiation beam that traverses an examination region and a subject therein; rotating the radiation source around the examination region about an axis of rotation; detecting radiation that traverses the examination region and at least a heart of the subject therein and generating image data indicative thereof; detecting an EKG signal, which includes a plurality of the heart cycles, for the subject; correlating the EKG signal with the image data; identifying a first plurality of time periods in a first heart cycle of the EKG signal; identifying a second plurality of time periods in a second heart cycle of the EKG signal; selecting first image data for one of the time periods of the first heart cycle; selecting second image data for one of the time periods of the second heart cycle, wherein the first and second image data correspond to a same overlapping sub-region of the heart and a similarity measure applied to reconstructed intermediate images generated therefrom is minimized; and reconstructing an image based on the first and second image data.
