摘要: An image reconstruction method comprises reconstructing an using iterative and computing a projection used in the by summing ray increments between neighboring planes (P0, P1, P2,...) parallel with detector face (42) stationary incremental blurring associated each increment computed based on distance planes. A non-stationary kernel may also be convolved at plane closest to generate incorporating shift-variant blurring.
