Abstract
Unambiguous reconstruction is not possible with truncated projections. In order to reduce the ambiguity in the reconstructed image, several authors have suggested that a simple 'completion' involving extrapolation of the truncated project- ion is sufficient. In this paper a method based on a Linear Prediction approach is proposed for obtaining the missing part in the projection. Reconst- ruction is then carried out using the Convolution Backprojection (CBP) method 111. Simulation results showing the effectiveness of this method in extracting significantly more information from truncated project- ions are presented.Keywords
