摘要
本文描述了评价一个射线照相系统空间分辨率能力的调制传递函数(MTF)方法,概括了确定它主要步骤,并且划出了在静态和连续运动状态下照相技术的 MIF 曲线.
This paper describes the Modulation Transfer Function(MTF)method which is used for evaluating the ca- pability of spatial resolution of a radiography system.The main steps for its determination are summarized,and MTF curves are developed for both static and continuous motion radiography techniques.
