What is Magnetic Resonance

Magnetic resonance has some microscopic particles and their electrons in the magnetic field which can produce some changes in the direction of the magnetic field. At the same time, its significance is also very wide. It is mainly applicable to some previous inspections. The sharing of magnetic resonance is that magnetic resonance is mainly discovered on the basis of the microscopic quantum theory of solids and some radio microwave electromagnetism. It mainly includes some ferromagnetic resonance, ferrimagnetic resonance and some traditional Chinese characters.

The basic principle of magnetic resonance imaging is mainly based on the principles of atomic electrons and the generation of some momentum. It is mainly used in daily life to examine the central nervous system, the five senses, the chest and abdomen, and the musculoskeletal system. Below we will briefly introduce what magnetic resonance imaging is.

Magnetic resonance refers to the phenomenon of spin magnetic resonance.

Its meaning is relatively broad, including nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) or electron spin resonance (ESR).

Magnetic Resonance Imaging (MRI) is mainly used for medical examinations.

2 Brief History of Development

Magnetic resonance was discovered based on the development of solid-state microscopic quantum theory and radio microwave electronics technology. In 1945, paramagnetic resonance was first observed in aqueous solutions of paramagnetic Mn salts. The following year, it was further observed using absorption and induction methods.

The nuclear magnetic resonance of protons in paraffin and water was discovered by the waveguide resonant cavity method; the ferromagnetic resonance of Fe, Co and Ni flakes was discovered by the waveguide resonant cavity method. In 1950, antiferromagnetic resonance of solid Cr2O3 was observed near room temperature. In 1953, cyclotron resonance of electrons and holes was observed in semiconductors silicon and germanium. Ferrimagnetic resonance was predicted theoretically in 1953 and observed experimentally in 1955. Subsequently, magnetostatic resonance (1957) and spin wave resonance (1958) of higher-order modes in magnetically ordered systems were discovered. In 1956, he began to study the magnetic double resonance phenomenon of two magnetic resonance couplings. After these magnetic resonances were discovered, they have been widely used in basic disciplines such as physics, chemistry, and biology, as well as new technologies such as microwave technology and quantum electronics. For example, paramagnetic solid-state quantum amplifiers, various ferrite microwave devices, nuclear magnetic resonance spectroscopy analysis technology and nuclear magnetic resonance imaging technology, and the use of magnetic resonance methods to study the crystal field and energy level structure of paramagnetic crystals, the band structure of semiconductors, and the structure of biological molecules. The determination of the spin and magnetic moment parameters of atomic nuclei and elementary particles is also developed based on various magnetic resonance principles.

The above is what magnetic resonance imaging is. It is mainly used for self-examination and some special examinations and its advantages in daily life are also very high. The main discovery technology is also a relatively high technology in imaging examinations. It is the principle that some atomic electrons and some momentum are generated. Therefore, doing magnetic resonance imaging disease examinations in daily life is also very critical.
