ABSTRACT:
Iterative algorithms, which may be used for image reconstruction, include alternating projections and backprojections usually have a slow convergence, due to correlations between simultaneously processed data. Consequently, a low image quality results. A filtering step is introduced before backprojection, allowing parallel processing without the loss of convergence speed or image quality. Advantageously, this allows several projections/backprojections to be performed simultaneously.
