Computing times. Computing times in case of established MAR algorithms are dominated by forward- and back-projections. Frequency split MAR (FSMAR) in addition requires a Gaussian blur filter which was excluded from the comparison due to an inefficient implementation for fairness. The MAR method described in this paper did not require any forward- or back-projections and features a low overall computing time.
