Rare earth elements (REEs) are widespread in nature, mainly concentrated in the earth's crust, but also in soil, water, atmosphere and living organisms. Rare earth elements and their compounds have become very popular in the field of medicine and biochemistry in recent years due to their special physico-chemical properties. Below, let's take a look at the application of rare earth mono-pole magnets in the field of medical imaging.
Rare earth mono-pole magnets are known for their strong magnetic field and stable performance. It is capable of generating high intensity magnetic fields in a small volume, which is critical for medical imaging equipment. In addition, the high magnetic field stability of rare earth mono-pole magnets ensures that imaging equipment maintains consistent image quality over long periods of time.
Magnetic Resonance Imaging (MRI) using rare earth mono-pole magnets uses a large, stable, uniform magnetic field to give the body a pulsed wave that causes the body's hydrogen atoms to resonate and absorb energy. The magnetic field is then suddenly turned off and the hydrogen atoms release the absorbed energy. After an electronic computer analyzes and processes the different information received, it can recover and analyze the images of the internal organs of the human body, which can be used to distinguish normal or abnormal organs and identify the nature of lesions.
Compared with X-ray tomography, MRI has the advantages of safety, no pain, no damage and high contrast. MRI does not use radiographic imaging and has no radiation damage to the body. It has a high soft tissue resolution and is able to clearly distinguish body tissues. Clear imaging of the heart and blood vessels can be performed without the need for additional drug injections. The ability to cut the layer directly in any direction makes it possible to observe all sides without changing the position of the examinee.
The application of rare earth mono-pole magnets not only improves the accuracy of clinical diagnosis, but also provides strong support for medical research. Through high-resolution MRI images, researchers are able to gain a deeper understanding of the internal structure and function of the human body, thus discovering new disease markers and treatments. In addition, the stability of rare earth mono-pole magnets provides a guarantee for long-term, continuous medical research.
In a word, rare earth mono-pole magnets are one of the important kinds of magnetic materials, which is a kind of magnetic material made by alloying samarium, neodymium and other mixed rare earth metals with transition metals (such as cobalt, iron, etc.), sintered by powder metallurgy, and magnetized by magnetic field. Compared with traditional permanent magnetic materials, rare earth mono-pole magnets have the highest coercivity and the largest magnetic energy product, and have become the key basic materials indispensable to modern industry.
