我院使用的CT-TIWN flash机X线部分故障稍多于其他部分。现将1例少见故障介绍如下,供同道们参考。 故障现象:开始时用250mA以上不能扫描,后来逐步降到100mA以下才能扫描,出故障时可以到达准备扫描状态,在启动扫描瞬间出错,终止扫描,操作系统故障信息报告为:HCU3006ERROR。 故障检查分析与维修:在操作台运行检修程序“ZMCU”,用120kv150mA曝光,即出上述故障。检查X线曝光状态表,表中示Ready Flags(准备状态代码)为:0X00B1,Interlock Flags(联锁电路状态代码)为:OXOOO2。这两组代码都不正常,前一组代码表示联
The X-ray part of the CT-TIWN flash machine used in our hospital has slightly more faults than other parts. Now a rare case is introduced as follows, for reference. Symptom: At the beginning, it can’t be scanned with more than 250mA, and then it can be gradually reduced to less than 100mA to scan. When a fault occurs, it can reach the ready-to-scan state. At the moment of starting the scan, an error occurs and the scan is terminated. The operating system fault information report is: HCU3006ERROR. Fault inspection analysis and maintenance: The operation and maintenance program “ZMCU” is operated on the console and exposed with 120kv 150mA, which means the above fault. Check the X-ray exposure status table. The table shows Ready Flags: 0x00B1 and Interlock Flags: OXOOO2. The two sets of codes are not normal.
