Analytic and iterative tomographic image reconstruction suffers from the time-consuming forward- and back-projection steps. We recently presented a set of acceleration techniques that improve the performance of forward- and backprojection on CPU (central processing unit) and CBE (cell broadband engine) -based platforms compared to straight-forward implementations by several orders of magnitude.
