Abstract：With the extensive and long-term use of the GE Voluson E8 color ultrasound system, ultrasound image failures are
gradually occurring. In order to carry out daily diagnostic work smoothly, it is necessary to quickly eliminate the failure. In this
article, two maintenance cases were summarized and analyzed: Voluson E8 BT12 version scanning area flower screen and Voluson
E8 BT15 version scanning area no image. First of all, we analyzed according to the principle of ultrasonic equipment composition,
confirmed the scope of the fault, then checked each fault point in detail, confirmed the fault, repaired the fault point, and finally
returned the device to normal operation by replacing the RFI image control board and the RFM image control board. We hope that
the method of troubleshooting in this article can provide a reference for the daily work of the majority of medical workers.
