Efficient Cone Beam Reconstruction For The Distorted Circle And Line Trajectory

Konate, Souleymane 01 January 2009 (has links)
We propose an exact filtered backprojection algorithm for inversion of the cone beam data in the case when the trajectory is composed of a distorted circle and a line segment. The length of the scan is determined by the region of interest , and it is independent of the size of the object. With few geometric restrictions on the curve, we show that we have an exact reconstruction. Numerical experiments demonstrate good image quality.
