Abstract:With the long-term and high-frequency use of ultrasound diagnostic instruments in clinical diagnosis, ultrasound diagnostic
systems have gradually entered a stage of frequent failures. In this paper, three failure phenomena of the GE Vivid7 ultrasound
diagnostic system were analyzed, including the blue screen at startup, black screen on the monitor and the device not starting caused
by the failure of the Southbridge and PC2IP board. According to the operating principle of the equipment, the fault was gradually
investigated. The equipment was restored to normal operation by replacing the ATX power supply, new hard disks, reinstalling the
system, adding welding and replacing the PC2IP board to the South Bridge. We hope that this study can enlighten the majority of
clinical engineers to actively master solid equipment operation principles and familiarize themselves with the relevant operations of
computer systems, so as to provide guarantee for the normal operation of equipment.
