ABSTRACT
Objective To study and analyze the quality safety of the ultrasonic diagnostic apparatus during clinical application to reduce the incidence of adverse events. Methods According to the actual use of ultrasonic diagnostic equipment and the data of quality control, the quality and safety factors of ultrasonic diagnostic apparatus during clinical application were studied by quantitative analysis of the ultrasonic source dose, image quality and etc. Results The factors affecting the quality safety of the ultrasonic diagnostic apparatus included the ultrasonic source dose, image quality, external environment and the operator's ability. Conclusion It is of great significance to understand the basic characteristics of the ultrasonic diagnostic apparatus and execute periodically preventive maintenance and quality control for increasing medical service quality while decreasing the incidence of adverse events.
