Four-treatment-room BNCT cancer treatment device based on high-current cyclotron

Abstract

The invention discloses a four-treatment-room BNCT cancer treatment device based on a high-current cyclotron. The four-treatment-room BNCT cancer treatment device comprises the cyclotron for generating negative hydrogen ions, a stripping target extraction structure for stripping the negative hydrogen ions into protons, beam transmission lines for sending beams to four treatment rooms, and four neutron target systems for uniformly capturing proton beams; the stripping target extraction structure is provided with two stripping targets which are symmetrically arranged on the cyclotron at 180 degrees; one end of each beam transmission line is led out from the stripping target, and the other end of each beam transmission line is connected with the neutron target system; and each neutron target system is connected with one treatment room, each beam transmission line corresponds to two neutron target systems and two treatment rooms, and the beam transmission lines are beam lines with radioisotope production target mechanisms. According to the four-treatment-room BNCT cancer treatment device based on the high-current cyclotron, the outstanding effect of reducing the cost of the four-treatment-room is achieved, and the same accelerator can be used for treating and producing medicines. Only hardware cost can be saved by more than 10 million yuan.

Description

technical field [0001] The invention belongs to the technical field of a cyclotron for medical cancer treatment, and in particular relates to a BNCT cancer treatment device with 4 treatment rooms based on a strong current cyclotron. Background technique [0002] BNCT (boron neutron capture) cancer treatment device is a new type of cancer treatment developed in recent years. It is one of the most advanced anti-cancer treatment technologies in the world. Its principle is to use non-radioactive boron isotope (boron-10) as tumor localization Drugs and Neutron Capture Agents. [0003] The diagnosis and treatment of cancer are divided into two stages. The first stage is before treatment. In the first stage, drugs for cancer diagnosis are injected into the human body for cancer diagnosis before treatment; the treatment process is the second stage. In the second stage, the drug used for cancer treatment is injected into the human body, and when the drug reaches a certain concentrat...

Problems solved by technology

[0007] In order to solve the problems existing in the prior art, the present invention proposes a BNCT cancer treatment device with 4 treatment rooms based on a high-current cyclotron. join online 18 F and other radioactive isotope production targets, to achieve the production 18 F-FDG (for cancer diagnostic drugs), and 18 F-BPA (used in cancer therapy drugs), 18 The purpose of the multipurpose drug of cancer diagnosis and treatment medicine such as F-BSH (for cancer treatment medicine); The second purpose is to solve the low utilization rate of the BNCT treatment device based on the single peeling target in the prior art, and it cannot meet the multi-flow intensity at the same time. The problem of distribution requirements; the third purpose is to solve the problem of complex structure and high production cost of realizing 4 treatment rooms BNCT cancer treatment device, peeling target and beam transmission line
