Ct-based Robot Gamma Knife Dose Field Analysis And Verification System

The Measure Analysis and QA System for Gamma Knife dose field and its pivotal technique are described in this paper. By using own measure tools and analysis software we make a testing analysis about the HuaYuan Gamma Knife dose filed.This method can reduce the time for measuring, speed up calculation and precision successfully. The relevant software have the functions, such as TMR/PDD data automatically self-recording, the physical precision, the dose filed parameter of Gamma Knife auto calculating and analyzing and so on.In this paper, we also introduce the analysis method and testing measure of a series of collimators applied in the HuaYuan Gamma knife system, involved the parameter of TMR,OAR, Scp. Efficiency of measurement and calculation are raided obviously.
