MRI-based IMPT planning for prostate cancer

For accurate dose calculations, Proton therapy planning requires the conversion of the computed tomography (CT) data from Hounsfield units (HU) to relative proton stopping power (RSP) according to an appropriate mapping [1]. That conversion prevents using other imaging modalities such as cone-beam CT, magnetic resonance imaging (MR), positron emission tomography, etc. for proton dose calculations.
