Summary: The purpose of this thesis is to validate the Monte Carlo algorithm forelectron radiotherapy in the Eclipse™ treatment planning system (TPS), and tocompare the accuracy of the Electron Monte Carlo algorithm (eMC) to the PencilBeam algorithm (PB) in Eclipse™. Dose distributions from GafChromic™ EBT3film measurements were compared to dose distributions from eMC and PBtreatment plans. Measurements were obtained with 6MeV, 9MeV, and 12MeVelectron beams at various depths. A 1 cm thick solid water template with holesfor bone-like and lung-like plugs was used to create assorted configurations andheterogeneities. Dose distributions from eMC plans agreed better with the filmmeasurements based on gamma analysis. Gamma values for eMC werebetween 83%-99%, whereas gamma values for PB treatment plans were as lowas 38.66%. Our results show that using the eMC algorithm will improve doseaccuracy in regions with heterogeneities and should be considered over PB.
