摘　　要：根据数字辐射成像的特点,提出了处理过程可视化的方法,并设计了可视化工具RDIvision,给出了使用该工具的具体例子。该实例表明,通过实现处理过程的可视化,可以更直观地设计算法,更有效评估算法的细节特性。Being closely connected with the physical mechanism of digital radiography, the process of reconstructing the image from projection data is rather complex. In order to give a deeper insight into the algorithm, we must turn to the visualization of processing. This paper designs and realizes a visualization tool (RDIvision) according to the characteristic of digital radiography. Then give an example about how to study the process in digital radiography with the help of this visualization tool. And it indicate the effectiveness of visualization of processing.
