Methods：In this study，the ultrasound reports of our department from January 2019 to December 2020 were quality controlled according to sub-specialty groups（abdominal group，vascular group，superficial organ group，heart group，obstetrics and gynecology group，interventional group）. The sub-professional team leader responsibility system is implemented under the leadership of the section director. The team leader is responsible for spot-checking all reports of the team on any working day of the team every month，according to the report description，report diagnosis，report save map three items and ten small items to make statistics，and calculate the report pass rate. Hold monthly quality control analysis meetings，point out common problems and typical individual problems，analyze and summarize the corresponding problems，and deploy continuous improvement measures. Compare the quality changes of the ultrasound report 3 months before and after the quality control analysis meeting. Results：By comparing the report quality of each sub-professional group in the three months before and after the quality control analysis meeting，the report qualification rate after the quality control meeting was significantly improved，and the difference was statistically significant（P < 0.05）.After the quality control meeting of the junior doctor group and the senior doctor group，the report quality qualification rate was significantly improved，and the difference was statistically significant（P < 0.05）.
