X射线管焦点尺寸测量方法研究
Study on Innovative Method for Measuring Focal Spot Size of X-ray Tube
摘要
Abstract
In this paper,an innovative method for the measurement of focal spot size was proposed,called the cone-hole method,which records the X-ray intensity distribu-tion at the edge of light field by using flat panel detector,with the help of the cone-hole.And then the focal spot size can be calculated.The operation and the measurement condition of this method are simple,and the experimental results show that the pro-posed method can measure the focal spot size efficiently.关键词
