摘要： 系统通过计算机对Ｘ光机的状态进行控制，对Ｘ光机摄取的静态和动态图象进行实时的捕捉、存储，能实现Ｘ光数字点片（ＰＤＳＩ）与数字减影（ＰＤＳＡ），并提供了大量的图象处理算法对捕捉的图象进行后期处理。简要地说明了该系统的设计和实现情况，并对其中动态减影新算法作了介绍。

Abstract: The System introduced here uses computer to control the X-Ray machine's status. It can grab and store the images that shot by the X-Ray machine in real time and it provides a plenty of algorithms to process the X--Ray images.The system also provides PDSI and PDSA in medical diagnoses.Both the design and implementation are presented in this paper.Especially,some impertinent image processing algorithms are also intToduced.
