A magnetic field and radio waves produced by a computer are used in the medical imaging procedure known as magnetic resonance imaging (MRI), which produces precise images of your body's organs and tissues.
Large, magnetised tubes make up the majority of MRI equipment. The magnetic field in an MRI machine causes your body's water molecules to momentarily rearrange. These aligned atoms emit tiny signals that are used to make cross-sectional MRI pictures, which resemble the slices of bread.
Additionally, the MRI scanner can create 3D images that may be viewed from various perspectives.
