| Abstract: |
We introduce general linear pre- and post- backprojection filters into the widely used simultaneous block iterative reconstruction algorithm, and show that the generalized algorithm converges, at linear speed, to a weighted least squares weighted minimum norm reconstruction, where the weighting matrices are determined by the filters. Our theoretical results expand several existing algorithms and open the possibility of selecting new filters. Examples of the application of our new theory are given. |
