Magnetic Resonance imaging Technique makes use of the RF Region of the electromagnetic spectra to provide an image.Even though it was started around 1946 by Felix block,who got nobal prize for MRI,now only it is popularized throughout the world.First a patient is placed in an external magnetic field which causes the magnetization of protons of hydrogen atoms in his body.Due to magnetization,these protons of hydrogen atoms in his body.due to magnetization,these protons align and precess about the external magnetic field.now a radio frequency pulse at resonance frequency is transmitted into the patient under controlled and prescribed condition.Due to resonance condition the individual protons responds by emitting a radio frequency signal.This is called nuclear magnetic resonance signal.These emitted signals by the protons,during their return from higher nuclear energy states to ground state,are picked up by RF coils and processed by computers using Fourier transforming techniques to produce an image.MRI has the foll, advantages over other medical advantages over medical imaging modalities.
