Classification: CPC A | IPC A

Claim 13:
14. A medical system, comprising:
at least one computer comprising a processor device;
at least one electronic data storage device storage surface data and/or planning data; and
a medical device for carrying out a medical procedure on a patient,
wherein the at least one computer is configured to perform a method of positioning the patient for a radiation treatment and/or of monitoring a position of the patient during the radiation treatment, including:
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,

wherein the at least one computer is operably coupled with:
the at least one electronic data storage device for acquiring, from the at least one electronic data storage device, at least the surface data and/or the planning data, and
the medical device for issuing a control signal to the medical device for controlling operation of the medical device based on the calculated first portion of the surface of the body part located inside the beam path and/or the calculated second portion of the surface of the body part location outside the beam path.
