Algorithms for image reconstruction using back projection with filtering by convolution for fan and parallel scanning geometry are described. The algorithm for regrouping projections from fan to parallel geometry is presented. Impact analysis of regrouping parameters (number of detectors, number of angle shots) of error level between images reconstructed in fan geometry and in parallel geometry after regrouping is discussed.
