• MC per nature delivers D m • For higher density materials, such as cortical bone, the difference in dose can be as large as 15%

• To use MC simulation in the current clinical practice so as to be able to compare D m with historical D w

results, requires a conversion of D m for dose prescriptions, isodose coverage, dose- volume histograms dose to a small volume of water embedded in the actual medium to D
