Paper Abstract

Limited-angle computed tomography was studied in a project to develop algorithms for a limited-angle scanner. Both the ART algorithm and an orthogonal function algorithm were investigated. The artifact produced by the different methods was very similar. A method is presented for producing model limited-angle artifact in phantom images. Filters are investigated for reducing the artifact, and it is shown that substantial improvement in subjective quality of images can be obtained. This method can be incorporated into limited-angle convolution back-projection algorithms.
