摘要
阐述了双能量X射线骨密度测量中使用的X射线源,介绍了产生双能量X线的两种方法,即K边过滤器法和高压切换法。重点介绍K边过滤器法的组成、特点和优点,并对这两种方法作了比较。
This paper described the X ray source in dual energy X ray bone density measure, introduced two methods of producing dual energy X ray, e.g.the K edge filter and the switched high tension and introduced the component, character and advantage of the K edge filter method mainly.
