The applications of superconducting technology in biomedical fields include superconducting magnetic resonance imaging devices (MRI) and nuclear magnetic resonance spectrometers (NMR). The principle of nuclear magnetic resonance imaging is to analyze the internal state of the tested object based on the resonance phenomenon between the atomic magnetic field and the external magnetic field of the tested object. At present, magnetic resonance imaging devices have been widely used in medical diagnosis, such as for early diagnosis of tumors and cardiovascular diseases. They can accurately examine the site of the disease, without damage or radiation, and have a wide diagnostic cross-section. The nuclear magnetic resonance spectrometer is developed based on the principle of nuclear magnetic resonance. It is currently widely used in research in fields such as physics, chemistry, biology, genetics, and medicine, with advantages such as high resolution, high frequency, and high magnetic field.
