Liquid target for medical isotope F-18 production

Abstract

The invention discloses a liquid target for medical isotope F-18 production. According to the present invention, water cooling is adopted to replace helium cooling, so that the structure is simplified. As the own spaces of a beam limiting flange, a connecting flange and a target body are fully utilized, no extra space is occupied independently, water channels are formed in the beam limiting flange, the connecting flange and the target body, and a helium cooling device does not need to be specially arranged between the front end of the target body and the beam limiting flange so as to cool a target window (a Half membrane), so that the length of the liquid target is shortened, and the structure is simplified. According to the present invention, after one or more elements are omitted, all original functions are still kept. During disassembly, only a first hoop needs to be disassembled, all parts at the right side of the first hoop can be integrally taken down and put into a waste box toremove the radiation, and meanwhile, an accelerator end cannot be exposed in the air for a long time to be oxidized due to overlong disassembly time, and the radiation time of workers by a beam current due to inconvenient disassembly and assembly is effectively shortened.

Description

technical field [0001] The invention belongs to the technical field of medical liquid targets, in particular to a liquid target produced by medical isotope F-18. Background technique [0002] The short-lived radioactive isotopes such as 15O, 11C, 13N, and 18F produced by small medical cyclotrons are themselves components of the body. The above-mentioned nuclides produced by the nuclear reaction of the production target are chemically synthesized through a synthetic module box. Various radioactive drugs participate in the human body. metabolism, while F-18's synthetic drug, 18F-FDG, mimics glucose metabolism. The application of 18FDG and PET-CT imaging can detect the primary and metastatic lesions of the whole body tumors early, and accurately judge the benign and malignant ones, so as to correctly guide clinical treatment decisions. [0003] The liquid target is a mechanism that completes nuclear reactions and generates positron nuclides. The beam enters the corresponding t...
