数字减影血管造影机的故障排除

Fault removal of digital subtraction angiography

在无电路原理图的情况下,对数字减影血管造影(DSA)机进行维修维护,得益于在工作实践中一些成功的经验和方法。如:使用一般的万用电表,跟踪电路板连线进行追踪,找出故障所在。仅仅依靠工作经验判断故障情况,当故障难度很大时便难以完成维修任务,应及时请原公司人员或是第三方有能力的人员维修。根据不同的情况灵活进行处理,提高处理速度,减少停机等待的时间。

In the absence of circuit diagram, the repair and maintenance of digital subtraction angiography （DSA） depend on successful experience and methods, such as using common multimeter and tracking circuit board connection to find out the faults. But difficult faults make the maintenance hard to complete only relying on the experience, so professional persons form the original company or a third party should be called timely for the maintenance, dealing with the faults flexibly so as to speed up the fault removal and shorten the downtime.
