In order to standardize the ultrasound procedures, and to improve the quality of ultrasound medical diagnosis and treatment, the ultrasound quality control system based on streaming media technology is designed and implemented according to the "Guideline for Ultrasonic Quality Control in Tier-3 Hospitals" issued by the ultrasound society of physicians of Chinese medical doctor association. Utilizing the characteristics of streaming media streaming and side pass and playing, the dynamic ultrasound images of the ultrasound clinic are transmitted to the chief supervisor in real time, and the real-time quality control of the ultrasound diagnosis process is accomplished through the supervision and evaluation of the director and remote assistance. At the same time, the system supports the dynamic deployment of client nodes, as well as different types of ultrasonic examination of packet quality control, which can protect the privacy of patients well. The system has been deployed in the department of ultrasound in Jiangsu Province People''s Hospital. Through the test and evaluation of the system from two aspects of delay and image quality, it shows that the system has the characteristics of low delay and high quality, and it is a feasible solution in practice.
