About

• A Magnetic Resonance Imaging (MRI) scanner is a medical device that uses a strong magnetic field and radio waves to generate detailed images of the inside of the body, particularly the soft tissues like the brain, muscles, and organs.
• MRI does not use ionizing radiation.

Functioning of MRI

• The strong magnetic field created by the MRI scanner causes the atoms in your body to align in the same direction. 
• Radio waves are then sent from the MRI machine and move these atoms out of the original position. 
• As the radio waves are turned off, the atoms return to their original position and send back radio signals. 
• These signals are received by a computer and converted into an image of the part of the body being examined.
