Abstract
This paper presents a variation on our Distance Driven projection and backprojection method in which the inner loop is essentially branchless. The new inner loop structure is highly parallelizable and amenable to vectorization or highly pipelined implementations. We demonstrate that the new loop structure computes the same results as the original method to within numerical precision.
