Optimizing the factorisation parameters in the fast factorized backprojection algorithm
Abstract
An explicit formula for optimizing the factorisation parameters in the fast factorized backprojection algorithm is given. It is shown that the optimal factorisation basis is given by b = 3, whereas the optimal number of factorisation levels can be easily computed a priori. A numerical example illustrates the effectivity of the proposed choice.
