METHOD FOR APPLYING ELECTRON BEAM IN CARRYING OUT RADIATION THERAPY Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves focusing magnetic field on flat boundary separating healthy tissues and those under radiation treatment. The healthy tissues are protected with magnetic field of high magnetic density not permeable to healthy tissues. The electron beam is directed at right angle to magnetic induction lines and at an acute angle relative to boundary plane between the healthy tissues and those under radiation treatment determined by electron reflection required for applying radiation. Electrons reflected by magnetic field are forced through tissues under radiation treatment and magnetic field properties are adjusted. Magnetic barrier impermeable for electrons on boundary plane separating healthy tissues and those under radiation treatment is used as magnetic field area possessing high magnetic field intensity. The barrier is curved in compliance with circular electron orbit arcs.

EFFECT: enhanced effectiveness in irradiating continuous and discrete-points areas.
