CT机已经成为临床医生特别是某些特殊科室人员的“左右”手,为临床上一些疑难疾病的诊断带来了极大的方便。河源某CT操作人员反映在临床操作过程中出现过以下两个故障:按下TC-300S控制台主机开关后,只有机架(GENTRY)能送上电,其它部分不能得电工作,及PICKER 1200SX型CT机故障电源稳压电路多个电容击穿,CT扫描过程中,kV显示表的电压跳动范围±5V,全幅图象模糊并呈严重噪声水波纹,不能做CT诊断。经处理后恢复正常。现整理成文,希望对同仁有所帮助。
The CT machine has become the “left and right hand” of clinicians, especially some special departments, which brings great convenience to the diagnosis of some clinically difficult diseases. Heyuan a CT operator reported that the following two faults occurred during the clinical operation: After pressing the TC-300S console host switch, only the GENTRY can be powered on, other parts can not be powered, and PICKER 1200SX CT machine fault power supply voltage regulator circuit multiple capacitor breakdown, CT scanning process, kV display table voltage jump range ± 5V, full-scale image is fuzzy and a serious noise ripple, can not do CT diagnosis. After processing, it returned to normal. It is now collated and I hope it will help my colleagues.
