SRT-100浅层X射线治疗系统辐射能谱的模拟研究
Simulation Study of Radiation Energy Spectrum of SRT-100 Superficial X-ray Therapy System
摘要
Abstract
Superficial treatment has shown good advantages in the repair of postoperative scars and the treatment of skin lesions.In order to study the radiation quality produced by SRT-100 superficial X-ray therapy system,EGSnrc software was used to simulate the energy spectrum at different tube voltages,and the energy spectrum was compared with the energy spectrum calculated by Spekcalc program.The result showed good agreement between them.The effect of different target angles of the X-ray tube on the half-value layer was studied,and the result showed that the larger the target angle,the smaller the half-value layer.The mean energy and the effective energy were calculated from the simulated energy spectrum.Compared with the results of Spekcalc,results displayed that the maximum deviation of the average energy and the effective energy are 0.7%and 5.8%respectively.关键词
