Analysis of Fault Cases of Color Doppler Ultrasound Diagnostic Instrument
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.
