Abstract

The invention discloses a medical radio isotope production system, and the system comprises an RFQ (radio-frequency quadrupole field) accelerator system and a target station device. The RFQ accelerator system is used for generating ions, and speeding up and conveying an ion beam. The target station device is connected with the RFQ accelerator system, and is used for leading the ion beam inwards, employing the ion beam for targeting so as to generate radio isotope and leading the radio isotope outwards. The system can achieve the application of the RFQ accelerator in the field of radio isotope production, is compact in structure, is small in size, is convenient to install, and is low in cost.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a medical radioisotope production system. Background technique [0002] Currently, radioisotopes have applications in many medical, imaging, and research fields. For example, in the field of medical applications, boron neutron capture therapy uses radioactive isotopes to treat cancer, and its basic principle is to use thermal neutrons to irradiate 10 B, 10 B captures a neutron to form an isotope 11 B, 11 B rapidly splits into heavy ions 7 Li and α, and then kill tumor cells. [0003] In the prior art, radioisotopes for clinical application can be obtained in various ways, such as accelerator production, reactor production, and extraction from fission products. Among them, in the production mode of accelerators, Radio Frequency Quadrupole (RFQ) accelerators are often used in the injectors of various accelerators because of their strong beam current, good quality, small size...
