Abstract

In this paper we review two algorithms proposed recently by one of the authors, for the inversion of spiral cone beam data. The algorithms have a filtered backprojection structure, and the filtering step is shift invariant. Both algorithms are based on the PI line idea and solve the long object problem. One of the algorithms is approximate, and the other one is theoretically exact. We discuss various theoretical properties of the algorithms, and illustrate their performance by the results of numerical experiments.
