Abstract

Proton therapy is a relatively novel cancer treatment technique that is often favoured if it is required that the healthy tissue that surrounds the tumour remains as undamaged as possible. A treatment plan can be determined by a combination of planning computed tomography and proton radiography. However, multiple Coulomb scattering inside the tissue causes proton radiography to be sensitive to uncertainties. In order to improve the accuracy of proton radiography, this study investigates the effect of the rejection of scattered protons by doing several Monte Carlo simulations. The accuracy of the corrected radiographs is shown to be improved for binning angles of 0.5, 0.75 and 1 degrees. By taking into account the contrast of the radiograph and the uncertainty in the data, the optimal binning angle is determined to be 0.75 degrees.
