Neutron capture therapy system

Abstract

The present application provides a neutron capture therapy system, which includes a neutron generating unit, an irradiation chamber, a preparation chamber, and an auxiliary positioner disposed in theillumination chamber and the preparation chamber. The neutron beam generating unit includes an accelerator for accelerating the charged particle beam, a neutron beam forming portion that generates that neutron beam by reacting with the charged particle beam, and the charged particle beam between the accelerator and the neutron beam forming portion and used for transmission of the charged particlebeam, the illumination chamber is a room for irradiating an irradiated body with a neutron beam, and the preparation chamber is a room for performing preparation work required to irradiate the irradiated person with the neutron beam, the auxiliary positioner is provided with a laser emitter that emits the laser beam to position the illuminated person, and the position of the laser emitter is selectable, and the irradiated body can be positioned in any case to achieve precise illumination.

Description

technical field [0001] The invention relates to a radioactive ray irradiation system, in particular to a neutron capture therapy system. Background technique [0002] With the development of atomic science, radiation therapy such as cobalt 60, linear accelerator, and electron beam has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the radiation itself. While killing tumor cells, it will also cause damage to a large number of normal tissues along the beam path; in addition, due to the different sensitivity of tumor cells to radiation, traditional radiation therapy For more radiation-resistant malignancies (eg, glioblastoma multiforme [0003] (glioblastoma multiforme), melanocytoma (melanoma)) are often poorly treated. [0004] In order to reduce radiation damage to normal tissues around the tumor, the concept of target therapy in chemotherapy (chemotherapy) has been applied to radia...

AI Technical Summary

Problems solved by technology

The traditional laser positioning system includes four laser emitters, which are fixedly installed on the walls and ceilings of the preparation room and the irradiation room respectively. Since the laser emitters are fixed, when the infusion tubes, treatment beds, etc. in the preparation room and / or irradiation room When objects block the laser beam, it is difficult to accurately position the patient, making it impossible to perform precise neutron beam irradiation treatment
