Abstract
The present invention, in one form, includes an imaging system having a x-ray source and detector array and a reconstruction algorithm. The algorithm removes overlapping structures from a patient scan so that enhanced images representing a moving heart are generated. More specifically and in one embodiment, an estimated background representing the overlapping structures is determined using the projection data. The estimated background is then subtracted from the projection data to generate filtered data. The filtered data is then used to generate an enhanced image so that cardiac calcification may be identified.
