FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, and can be used in hadron radiation therapy of malignant tumours. The method involves the pre-radiation preparation consisting in fixing a patient, evaluating the topographometric parameters of the malignant tumours, developing a conformal irradiation session. Conducting the conformal irradiation session is combined with regulating a radiation dose received by the malignant tumour, adjusting the acceptable values of irradiation source parameters, a radiation background, temperature values of various places of the irradiation source and magnetooptical chain of beam delivery of the malignant tumour. During the pre-radiation preparation and conformal irradiation session, the patient is fixed in an identical adjusted position, the topographometric parameters 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 gastric 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 complex comprises a charged particle generator connected through a multichannel magnetic radiation transporter to a multichannel radiation therapeutic apparatus supplied with radiating heads, a cryogenic station, a gas refrigerator unit, a control and alarm equipment, and also a digital control means subsystem. 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 radiation therapeutic 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 evaluators in the form of heat-sensitive sensors 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 gastric tumour during respiration not injuring the adjacent healthy tissues and organs.
