Paper Abstract

We develop a reconstruction algorithm for local cone-beam X-ray tomography for use with generalized scanning trajectories. The algorithm is based upon an extension of a recently-developed chord-based theory for exact conebeam image reconstruction. Being chord-based, it is distinct mathematically and conceptually from conventional local tomography reconstruction algorithms. A computer-simulation study is conducted to demonstrate the algorithm, and compare its performance to an existing algorithm.
