Dose calculation algorithm differences

▪ AcurosXB

▲Collapsed Cone

In this comparison the original plan was calculated using Collapsed Cone algorithm on a Varian IX machine with Millenium 120 MLC. The plan and dose where imported into Eclipse. The plan was copied and recalculated with fixed MU and then normalised to 95% coverage at prescription dose with both AAA and AcurosXB
