Abstract：With the development of ultrasonic diagnostic equipment in hospitals, it plays a crucial role in clinical diagnosis. Because of the long and high frequency of usage, ultrasonic diagnostic system has gradually entered the stage of frequent malfunction. In this paper, the malfunction of SYSCONML board of Logiq ultrasonic diagnosis equipment caused image interference, the malfunction of DTRX64 board caused image loss, and the transistor malfunction of APSII led to the Transbox power insurance fuse, which made it impossible to return to normal function. According to the operating principle of the equipment, the system was gradually investigated, and was restored to normal operation by replacing the transistor of SYSCONML board, DTRX64 board and APSII. Through the study of this paper, we hope to let the majority of clinical engineers understand the operating principle of ultrasonic equipment and provide guarantee for the operation of the equipment.
