摘要
A method of positioning a patient for a radiation treatment and/or of monitoring a position of a patient during a radiation treatment is provided. The method includes providing surface data acquired using a 3D surface scanner of a surface of at least a body part of the patient that is to be irradiated in a radiation treatment. 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. A beam path and/or frustum of a radiation beam is determined based on planning data for the radiation treatment and intersected with at least a part of the surface of the patient represented by the surface data. Further, at least a first portion of the patient's surface located inside the beam path and/or a second portion of the patient's surface located outside the beam path is calculated.
