Abstract

It is known that cone-beam projection measurements from a single planar orbit of the focal point do not satisfy Tuy's sufficiency condition for exact reconstruction. It is also known that two such orbits, oriented orthogonally, do satisfy the condition. In this paper, we present a fast convolution-and-backprojection algorithm to perform reconstructions from two orbits of cone-beam data. The algorithm has been applied to simulated data, and phantom data taken on a clinical SPECT system.
