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, thereby affecting the effectiveness of teaching. This study discussed the basic issues regarding the teaching of magnetic resonance physics for the first time by utilizing MRiLab magnetic resonance simulation software. The results indicate that MRiLab magnetic resonance simulation software can vividly visualize the evolution of the magnetization vector and accurately calculate the variation curves of magnetic resonance transverse and longitudinal magnetization vectors. It facilitates students’ deep understanding of the basic concepts of magnetic resonance physics in teaching.
