摘　　要：文章对X线CT的x线发生系统的组成结构及其工作原理进行了简要的分析,介绍了各种控制信号之间的相互关系;本文重点对X线CT系统中x线发生系统的常见故障的成因进行了说明,并特别介绍了连锁保护各种信号形成的原因,以及当出现这些故障时的应急处理方法。加深医院中x线CT维修与维护人员对于X线CT中X线发生系统的全面理解,对X线CT的日常维修与维护提供一些帮助。Because of the lack of systematic studying and training on the structure of X-ray CT scanner in the X-ray technicians in hospital, we tried to comprehensibly describe the structure and their working principle of X-ray generation system in X-ray CT scanner, and the relationship among the different control signals of X - ray generation system in X-ray CT scanner. The explanations aboutthe common breakdowns of X-ray generation system in X-ray CT scanner were stated; especially the principle of generation of the locking protection signals. We wish this article can help the engineers in hospital for understanding X-ray generation system in X-ray CT scanner, and give some aids in treating common breakdown in X-ray CT system.
