METHOD OF HADRON BEAM IRRADIATION OF MALIGNANT PULMONARY TUMOURS AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2011 - IPC A61N5/10 G21G4/00 H05H13/04 H05H7/08 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, and can be used in beam therapy of malignant tumours. The method involves pre-beam preparation consisting in fixation of a patient, evaluation of topographometric parametres of malignant tumours, development of a conformal irradiation procedure considering the topographometric parametres of malignant tumours, adjacent tissues and bodies critical to irradiation, a conformal irradiation session with controlling a dose produced by the malignant tumour, admissible parametres of an irradiation source, a radiation background, temperature of various irradiation source regions and magnetic optical chains of beam delivery to the malignant tumour. During the pre-beam preparation and conformal irradiation session, the patient is fixed in an identical adjusted position, the topographometric parametres of the malignant tumours are evaluated, and a hadron beam is delivered to the malignant tumour of the patient in the form of an enable pulse of beam delivery to the malignant pulmonary tumour during a respiratory pause of the patient in the absence of cardiac beat pulse wave peak with a constant size of a thorax. A therapeutic proton-ionic complex comprises a charged particle generator connected through a multichannel magnetic radiation transporter to a multichannel beam therapy apparatus supplied with radiating heads, a cryogenic station, a gas refrigerator unit, a control and alarm equipment, and also a digital control means subsystem with its driving output connected to an beam delivery enable input of the charged particle generator. The charged particle generator is supplied with accelerating and deflecting magnets, while the multichannel magnetic radiation transporter comprises transporting and deflecting magnets, and the irradiating heads of the beam therapy apparatuses have scanning and focusing magnets. All magnetic windings are superconducting and have the cooling channels connected by a gas-vapour mixture of the cooling agent with the cryogenic station, and by a gas cooling agent - with the gas refrigerators. In addition, the complex accommodates physiological feedback means comprising time respiratory parametre means in the form of heat-sensitive sensors reacting to cold air in inhalation and on hot air in exhalation or optical electronic sensors reacting on the thorax size variation in respiration, and cardiac beat pulse wave in real time located on the patient's body.

EFFECT: use of the invention allows more precise irradiation of the malignant pulmonary tumours during respiration not injuring the adjacent healthy tissues and bodies.
