摘要
根据光线追迹原理建立了X射线在圆柱形直导管中传输的计算模型,使用Matlab语言完成了相应的计算程序.对X射线在圆柱形直导管传输后的光强分布规律进行了研究和总结.结果表明,圆柱形直导管有会聚X射线的作用.
Based on the ray-tracing theory, a calculation model for .X-ray transmission in a cylinder capillary is set up. Using the Matlab program, the intensity distribution curve through a capillary is calculated. The transmission regularity of X-ray through a cylinder capillary is studied and concluded. The results are that a cylinder capillary has convergent function.
