METHOD FOR CONTROLLING BEAM PARAMETERS DURING PROTON THERAPY AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: invention is used to control the beam parameters during proton therapy. The essence of the invention lies in the fact that the measurement of the permissible values of the density of the beam intensity before irradiation of the patient is carried out using coordinate-sensitive detectors installed in front of the patient and behind the last scanning magnet, the quantitative comparison of the measured parameters of the intensity density with the permissible values and the shutdown of the beam when the parameters deviate from the permissible values, while measuring the permissible values of the density of the beam intensity additionally includes measuring the depth of the Bragg peak by means of a device for measuring energy release from ionizing radiation, installed at the patient's site, with the possibility of its subsequent removal from the beam axis when the patient is irradiated, and pad detectors are used as coordinate-sensitive detectors cameras on "warm liquid".

EFFECT: invention is aimed at increasing the conformity of proton therapy due to constant monitoring of the dose field boundary in the target.
