It is anxious.Nuclear magnetic resonance：The various magnetic fields used in " magnetic " presentation technology in title, " resonance " refer to the frequency of external radio frequency with
Nuclear " precession " the frequency matching of certain in tissue element.Magnetic resonance imaging is perhaps the more scientific title of this technology,
But it is due to the public couple and the baffled worry of " core " about vocabulary, eliminates " core " word when stating this technology, the current public
All with " MRI ", this abbreviation represents this imaging technique with professional person.In fact atomic nucleus only plays the part of the angle of " spin " in
Color, has no injury to human body.Hydrogen Proton can have inherent angular momentum to be rotated around magnetic direction under being acted in extraneous stationary magnetic field,
The angular momentum wherein rotated is directly proportional to the stationary magnetic field.If above-mentioned magnetic field is slowly varying, then Hydrogen Proton also can be with
The angular momentum slowly changed rotates around magnetic direction.And then we obtain the characteristic, the object for possessing large quantity of moisture is carried out
