[0002] Magnetic resonance scanning technology is a method of scanning using magnetic resonance imaging (MRI) technology. MRI is a non-invasive examination technology that uses strong magnetic fields and radio frequency pulses to resonate hydrogen nuclei in the human body, thereby generating signals to construct images of the inside of the body. Magnetic resonance radiological diagnosis has a wide range of applications in the medical field. It can clearly display various tissue structures and pathological conditions inside the human body, providing doctors with important diagnostic basis. However, the process of magnetic resonance scanning takes a long time, and is accompanied by a lot of noise.
