ABSTRACT:
A method and system for suppressing artifacts in a CT generated image are described. With respect to artifacts resulting from X-ray beam photon starvation conditions, and in accordance with one embodiment of the method, the steps of determining a minimum value X-ray beam flux for a projection data set and dynamically DC adjusting the projection data based on the determined minimum X-ray beam flux are performed.
