X射线管出射谱源项及过滤谱的蒙特卡罗模拟
Monte Carlo Simulation of Emitted Source Term and Filtered X-ray Spectra by X-ray Tube
摘要
Abstract
Monte Carlo method was used to calculate the emitted and filtered spectrum which were produced by X-ray tube,the effects of Be window and target angle on emitted spectra were discussed,and the heel effects under different tube voltages and target angles were also calculated.The simulated X-ray spectrum after filter at a distance of 1m from focal spot was compared with measured X-my spectrtm by PTB.The results show a good agreement between the simulated and measured X-ray spectrum,which verified the validity of the Monte Carlo method in simulating X-ray spectrum and the effectiveness of the model.关键词
