Abstract: Objective: medical image processing is one of the important professional courses of Biomedical Engineering and medical imaging technology. In order to further improve the teaching effect of medical image processing practice course, this paper discusses the application of PBL(Problem-Based Learning) combined with CT(Computed Tomography) simulator in the teaching of medical image processing practice course. Methods: real cases with certain frontier were designed and PBL teaching method was used to carry out teaching activities, focusing on improving students' autonomous learning ability. CT simulator can simulate the working process of real CT and display various processing effects of CT images, so as to cultivate students' practical operation skills of hardware and software of large imaging equipment. On the basis of PBL, in view of the problems designed, scene teaching is carried out by using CT simulator. Results: to cultivate the students' practical operation ability for large imaging equipment, improve the enthusiasm and initiative of students in course learning, and improve the medical humanistic quality of students. Conclusion: PBL teaching method combined with CT simulator can effectively improve the teaching effect of medical image processing practice course.
