摘　　要：超声诊断仪因其高精度成像能力和广泛应用,已成为临床诊断中不可或缺的工具。本文针对3个不同型号的GE医疗超声诊断系统(LOGIQ E9、VIVID E9和Voluson E8),分别对其启动无信号输入、无响应且指示灯未亮以及开机无响应但按键灯亮的故障进行分析,通过使用万用表、示波器和逻辑分析仪等多工具进行故障诊断与排查,确定故障点分别为内存插槽、主电源故障、视频中断线缆,最终通过修复排除故障。本文通过对维修过程的深入分析,利用系统化维修流程及逻辑推理,提升了故障诊断的精确性和维修效率,有助于提升设备的稳定性和延长使用寿命,可为同行提供参考借鉴。Ultrasonic diagnostic instrument has become an indispensable tool in clinical diagnosis because of its high-precision imaging ability and wide application.Three different types of GE medical ultrasound diagnosis systems(LOGIQ E9,VIVID E9 and Voluson E8)were analyzed for their failure of starting without signal input,no response and indicator light off,and starting without response but key light on.Through the use of multimeter,oscilloscope logic analyzer and other tools for fault diagnosis and troubleshooting,the fault points were determined to be memory socket,main power failure,video interrupt cable,and finally the fault was eliminated by repair.Through in-depth analysis of the maintenance process,this paper used systematic maintenance process and logical reasoning to improve the accuracy and maintenance efficiency of fault diagnosis,which is helpful to improve the stability of equipment and prolong the service life,and can provide reference for peers.
