Results of the academic phantom with adjacent inhomogeneities. Integrated depth dose curves (top) with corresponding dose difference (DD) and 1D gamma evaluation (middle) and contour plot (bottom) for the academic phantom with lung and cortical bone adjacent to each other for mono-energetic proton 4×4 cm2 broad beams of 100 MeV, 150 MeV, 200 MeV and 250 MeV. Lines are for the adaptive pMMC (dashed), non-adaptive pMMC (dotted) and Geant4 (solid). The isodose lines indicate 10%, 20%, 40%, 50%, 60%, 70%, 80%, 90%, 95% and 99% of the respective reference dose maximum
