ABSTRACT:
A fluoroscopy imaging system which, in one embodiment, includes a modified halfscan image reconstruction algorithm which provides acceptable image quality along with the benefits of an enhanced temporal response as compared to the OS algorithm, is described. In an exemplary embodiment, the algorithm includes the steps of dividing the projection data into a preselected number of subsets, and for each subset, two partial images are generated: one with a first set of weights (denoted by T.sub.i) and the other with a second, i.e., unity, set of weights (denoted by U.sub.i). The final image, P.sub.i, is generated from the two partial images.
