Abstract: Magnetic Resonance Imaging（MRI) technology is one of the most important techniques in medical imaging. Magnetic resonance physics is the basis for understanding magnetic resonance imaging. However, the theory of magnetic resonance physics is complex and abstract, which makes it difficult for students to understand and then affect the effectiveness of teaching. This study discussed the basic issues in the teaching of magnetic resonance physics for the first time by integrating MRiLab magnetic resonance simulation software. The results indicate that MRiLab magnetic resonance simulation software can show the change process of magnetic resonance magnetization vector vividly and calculate the change curves of magnetic resonance transverse and longitudinal magnetization vector accurately. It helps students to understand the basic concepts of magnetic resonance physics deeply in teaching.
