To meet the demand for training innovative and excellent biomedical engineering talents under the "New Medical + New Engineering" framework and to improve the teaching quality of the medical image processing course, our team has reformed and implemented a new course design. Based on the UbD (Understanding by Design) theory, we emphasize medical applications and integrate medical image processing techniques with advanced technologies such as artificial intelligence, big data, and 5G communication. The course was implemented in the sixth semester of Biomedical Engineering major in our university. This course design prioritizes understanding as the primary teaching goal, ensuring clear objectives, content aligned with the "New Engineering + New Medical" framework, and assessment methods that effectively evaluate students' comprehension. The practical implementation has demonstrated high student satisfaction.
