Objective: To explain the principle and application of pulsed nuclear magnetic resonance imaging experiment apparatus. Methods: The structure and principle of pulsed nuclear magnetic resonance apparatus were analyzed and discussed, and its effect was verified by practical application. Results: It is proved that the pulsed nuclear magnetic resonance apparatus can intuitively understand the basic principle and the realization process of the nuclear magnetic resonance technique. At the same time, it can also understand the mathematical treatment methods of various pulse sequence principles and image reconstruction, as well as various artifact generation mechanisms and pulse parameters Set the impact on the image, one-dimensional two-dimensional three-dimensional imaging studies. Conclusion: The pulsed NMR imaging instrumentation provides one of the most intuitive ways of understanding MR imaging principles and underlying techniques for those involved in MRI.
