Abstract
Systems and methods are presented for decreasing the processing time of spectral artifact reduction systems that use reprojection data for post reconstruction corrections. The systems and methods essentially reduce the data processed for the reprojection step to reduce the normally relatively long time period required by reprojectors. The time savings have no detrimental effect on image resolution. Thus, better quality pictures are obtained in shorter time periods.
