How does an mri machine work video. Magnetic resonance imaging mri is a non invasive imaging technology that produces three dimensional detailed anatomical images. A powerful primary magnet creates a magnetic field that s much stronger than even the magnetic field given off by the earth. Mri short for magnetic resonance imaging machines use high powered magnets to create incredibly detailed images of the body. A basic description of how does the mri work no quantum physics no rocket science.
Magnetic resonance imaging mri is a medical imaging technique that uses a magnetic field and computer generated radio waves to create detailed images of the organs and tissues in your body. This is for anybody. Mri scanners look deep inside your body to produce detailed images.
