Claim 12:
13. A computer program product comprising a non-transitory computer readable storage medium storing a computer program containing program instructions, that when executed on at least one processor of the computer or when loaded onto the at least one processor of the computer, causes the computer to perform a method of positioning a patient fro 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.
