PROTON THERAPY METHOD IN TREATING ONCOLOGICAL DISEASES Russian patent published in 2019 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment and can be used in treating oncological diseases by proton therapy. Method of proton therapy in treating oncological diseases involves forming a directed proton beam and a two-dimensional tumour projection in a plane perpendicular to the proton beam, tumour depth is measured, a two-dimensional tumour projection is scanned with a proton beam to the tumour depth and selecting during scanning the energy of the directed proton beam in accordance with the depth of the tumour location, wherein the directed proton beam is formed in form of a focused beam, and the focal position is changed when scanning to the depth of tumour location, providing successive movement of the beam along the external surface of the tumour, wherein the scanning rate is set at each point on the external surface of the tumour, taking into account the intensity of the proton beam and the diameter of the beam in the focus, providing destruction of the exposed tissues on the external surface of the tumour with dose of 50–80 Gy.

EFFECT: use of the invention widens the range of technical means used in proton therapy of oncological diseases.
