Decreasing the PTV margins in IMPT using Monte Carlo with incorporated random setup errors

M. Soukup & M. Alber
Background: To handle calculation and geometric uncertainties like random setup error, planning margins are added to the Clinical Target Volume (CTV) in common treatment planning. However, the margin concept can lead to an over-irradiation of healthy tissue and unnecessary trade-offs in target coverage.[for full text, please go to the a.m. URL]
