在ＣＴ扫描过程中,床下钢丝绳起到自动驱动床面的作用。若钢丝绳发生损坏,床面自动驱动停止,扫描自动停止。由于扫描床钢丝绳损坏,直接影响整机扫描工作。在此情况下,我们用二胡琴弦替代钢丝绳效果非常满意。1　故障于1996年12月正在扫描中,扫描突然终止,停机检查;计算机、Ｘ线 During the CT scan, the bed wire rope plays a role in automatically driving the bed.

In this case, we are very satisfied with the replacement of wire rope with erhu strings. 1 failure in December 1996 scanning, abrupt termination of scanning, downtime check; computer, X-ray
