METHOD OF CARRYING OUT IRRADIATION OF MALIGNANT LIVER TUMOURS WITH BEAMS OF HADRONS AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC A61N5/10 G21G4/00 G21G1/00 H05H13/04 H05H7/08 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment and can be used in carrying out radiotherapy of malignant tumours. Method includes carrying out pre-radial preparation, which includes patient fixation, determination of topometric parametres of malignant tumours, elaboration of procedure of conformal irradiation, taking into account topometric parametres of malignant tumours, closely located tissues and organs, critical to irradiation, carrying out a session of conformal irradiation with control of dose received by malignant tumour, permissible values of irradiation source parametres, radiation background, temperature of various sites of irradiation source and magneto-optical chains of beam delivery to malignant tumour. During pre-radial preparation and during session of conformal irradiation patient is fixed in identical adjusted position, topometrical parametres of malignant tumours are determined and beam of hadrons is delivered to patient's malignant tumour in form of pulse of resolution/permission of beam supply onto malignant lung tumour at the moment of pause between patient's inhale and exhale in case of absence of peak of pulse wave of heart beats with constant dimensions of chest. Medical proton-ionic complex contains generator of charged particles, connected via multi-channel device of magnetic transportation of irradiation with multi-channel radiotherapy device provided with radiating heads, cryogenic station, unit of refrigerating gas machines, equipment of control and alarm signalling, as well as subsystem of digital means of control, whose control outlet is switched to inlet of permission of beam supply of charged particles generator. Generator of charged particles is provided with accelerating and deviating magnets, multi-channel device of magnetic transportation of irradiation - with transporting and deviating magnets, and irradiating heads of radiotherapy devices - with scanning and focusing magnets. Windings of all magnets are made superconductive and are provided with channels of cooling, connected via vapour-gaseous mixture of cooling agent with cryogenic station, and via gaseous cooling agent - with refrigerating gas machines. Additionally complex contains means of physiological feedback, which include means, determining time parametres of breathing in form of thermally sensitive sensors, responding to cold air during inhale and to hot air during exhale or optoelectronic sensors, responding to change of chest dimensions during patient's breathing, and pulse wave of patient's heart beats in mode of real time, placed on patient's body.

EFFECT: application of invention makes it possible to irradiate malignant tumours of liver more accurately in process of patients' breathing without trauma to closely located healthy tissues and organs.
