Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Figure 1a It is a schematic diagram of the overall structure of the radioactive source protection plug moving device according to the present invention, Figure 1b It is a top view of the radiation source protection plug moving device according to the present invention. Before starting to change the source of the Gamma Knife, first remove the protective plate at the bottom of the Gamma Knife main body plug, and then move the radiation source protection plug out of the Gamma Knife main body to perform the source change operation. During the entire moving process, it is necessary to keep the...

Abstract

The invention discloses an automatic source converter for a gamma knife and a method thereof. The automatic source converter comprises a radioactive source protection plug shifter and a six-degree-of-freedom mechanical hand (15), wherein the protection plug shifter comprises a supporting plate (3) for supporting a radioactive source protection plug, an X-shaft guide rail (7) and a Y-shaft guide rail (4) which are communicated with each other and form a T-shaped guide rail as well as a traction mechanism (1) used for pressing closely, positioning and firmly being connected with the protection plug and then pulling the protection plug out of a mainframe of the gamma knife through the T-shaped guide rail; and the six-degree-of-freedom mechanical hand (15) is used for taking out and replacing radioactive sources. According to the invention, during shifting, the protection plug can be kept being positioned precisely so as to facilitate reinstallation, the source conversion operation is performed automatically, manual intervention can be performed at will, and the problem of radiation injury caused by manual source conversion is solved.

Description

technical field [0001] The invention belongs to the technical field of radiation, and more specifically relates to an automatic source replacement device and method for a gamma knife. Background technique [0002] Gamma Knife is a non-interventional radiotherapy device used to treat cancer. According to the principle of stereogeometric orientation, the diseased tissue in the brain or in the body is selectively determined as the target, and the gamma rays generated by cobalt-60 are used for treatment. One-time high-dose focused irradiation to cause focal necrosis or functional changes to achieve the purpose of treating diseases. It has the advantages of accurate target, high dose rate, short treatment time and high tumor control rate, so it has been widely used at home and abroad in recent years. However, since cobalt-60 as a radioactive source will gradually decay over time, its dose will be reduced by half every 5.27 years. Therefore, regular source replacement is required...
