Claim 0:
1. A computer-implemented method of positioning a patient for a radiation treatment and/or of monitoring a position of the patient during the radiation treatment, the method comprising:
providing surface data from a 3D surface scanner, wherein the surface data are indicative of a surface of at least a part of a body part of the patient to be irradiated in the radiation treatment, and wherein the surface data are calibrated with respect to a relative position of the 3D surface scanner and an isocenter position of a radiation treatment apparatus;
reconstructing a beam path of a radiation beam based on planning data for the radiation treatment; and
calculating, based on intersecting the surface and the reconstructed beam path, at least a first portion of the surface of the body part located inside the beam path and/or at least a second portion of the surface of the body part located outside the beam path.
