APPARATUS FOR REMOTE NEUTRON THERAPY

摘要

FIELD: medicine.SUBSTANCE: apparatus for remote neutron therapy is intended for treating of radioresistant forms of oncologic diseases. Its construction includes a base, providing ±180° rotation of a balanced console with a neutron head. The neutron head consists of a neutron generator, a radiation protection with an in-build in it neutron channel. In the generator as a source of neutrons a nuclear reactionT(d,n)He is applied. The neutron head is placed on the balanced console with a mechanism of its longitudinal travel. Different sizes of neutron fields on the patient's body are formed by means of wedges. To measure the distance from the source of neutrons to the patient there is a laser or a microwave ruler and a video camera with LEDs for visualising superposition of the marked contour of irradiation on the patient's body with an image of the output opening of the neutron channel. To reduce an impact of directed radioactivity on the attendant personnel the cooled substrate of the target and walls of the neutron channel are made from selected materials, also introduced is a protective box for placement of the neutron head in it by a robotised device during the patient's positioning.EFFECT: invention makes it possible to reduce exposure of the personnel to radiation.9 cl, 2 dwg
