Understanding obscure concepts and calculating complex mathematical equations are the essential issues and challenges in the courses of medical physics. To enhance the effectiveness of lectures, it is crucial to display spatial structures and dynamic processes visually. In this study, Young's double slit interference, simple harmonic vibration equation, refractive error, and correction of the eye are selected by questionnaire, and 3D Max is employed to construct their 3D dynamic models. The corresponding courses are then designed and assisted by using virtual experiment teaching. This approach enriches the expression form of abstract physical processes, innovates classroom knowledge presentation and provides references for updating the teaching mode of medical physics and deepening curriculum reform.
