Magnetic Resonance Imaging (MRI) is a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring.

MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body. They differ from computed tomography (CT), in that they do not use the damaging ionizing radiation of x-rays. The brain, spinal cord and nerves, as well as muscles, ligaments, and tendons are seen much more clearly with MRI than with regular x-rays and CT; for this reason MRI is often used to image knee and shoulder injuries.

In the brain, MRI can differentiate between white matter and grey matter and can also be used to diagnose aneurysms and tumors. Because MRI does not use x-rays or other radiation, it is the imaging modality of choice when frequent imaging is required for diagnosis or therapy, especially in the brain.

MRIs employ powerful magnets which produce a strong magnetic field that forces protons in the body to align with that field.  Magnet is the core component of the MRI system, and its magnetic field strength, stability, and uniformity have a great influence on MRI images.

The permanent magnet produced by CSJ, which can be used for whole body inspection, adopts high-performance rare earth permanent magnet materials,  eddy current suppression design, optimizes the magnet structure, occupies a small area, low installation costs, and has a high degree of openness, low system maintenance and operating costs.
