| the Gamma-knife is the large curing device which has developed about 30 years. It is the high technology curing device for resolving the problem of ablating the knub from the sufferer that the surgical operation can not resolve.The invention of the Gamma- knife makes the removing the knub from the sufferer without surgical operation into reality.It provides the sufferer a safe, credibility, conveniency, effective curing method without surgical operation, hurt, suffering, infection, Hocus of the body. And it provides the sufferer (suffering the thalamencephalon pathological changes) who cannot suffer the surgical operation a safe curing method.development status of the Gamma -knife are briefly reviewed home and abroad. Eximious advantage of the Gamma -knife is introduced.The manufacturing history & development ,variety, radiotherapy theory of the Gamma -knife are involved. The emphasis are the structure and characteristic of theγ-radial bodyfix stereotactic device with original structure(called "moon deity" in this article), difficulty of the research & manufacture, assuring the precision of the double-focalizing, moon arm, curing head, cobalt source box, collimation, lifting spindle, 3d curing bed .and introduced the disposal of the moon arm, 3d curing bed distortion.Next, the article involves the static state focusing center, dynamic camber irradiation focusing center, the research of the 3d curing bed Revolution centre assembly and debug and makes the 3 centres concentric .at the same time, analysis the R/M process about the manufacturing process and the precision.Next, the author performs the 3d disassemble of the focusing centre precision.The author analyses the process of the research & manufacture detailedly; describes the transfer, dispose, control of the benchmark in the manufacturing process; analyses the development of prospect & economy benefit.The author establishes the theory of the 3d real time compensating system. |
