Analyze the feasibility of using the breast simulation phantom in the teaching of ultrasound professional discipline. Methods: The students who were trained in the First People"s Hospital of Hangzhou in December 2018 were selected as the experimental group and the advanced students as the control group. The breast simulation phantom was applied to the discipline training and advanced theory and operation techniques were trained. Through the operation test, theoretical test, after-school questionnaire survey, etc., the teaching effect analysis. Results: 21 patients in the experimental group and 8 in the control group. After the training, the theoretical test scores were 68.10±8.14, and the control group was 50±12.24, which was statistically significant. In the different stages of the same grade, the difference in the scores of the operation was statistically significant (F=106.59 P=0.00), and 100% of the participants in the questionnaire believed that they benefited from the relevant study. Discussion: The advantage of the application of the breast phantom in the ultrasound regulation teaching is that it is convenient for the doctor to understand the anatomical relationship during the teaching, and it is convenient for the boys to practice the sensitive parts. The disadvantage is that the lesion image and position are fixed, which is not conducive to the improvement of the business ability of the senior grade.
