Health field, i.e., be subject to the excitation of radio-frequency pulse using hydrogen nuclei in tissue (proton) in magnetic field and nuclear-magnetism occur and is total to
Shake phenomenon, produce magnetic resonance signal, handled by electronic computer, reconstruct the imaging technique of the image of a certain aspect of human body.
The basic principle of magnetic resonance imaging is：The atom of some protons containing odd number in tissue, such as hydrogen atom can spin fortune
It is dynamic, and produce magnetic moment, it can be seen as some small magnets, under normal condition, the spin direction arrangement of those small magnets is irregular, but
It can produce and align under fixed main field effect；At this time, when the radio-frequency pulse of additional one and main field identical frequency,
These hydrogen atoms absorb certain energy and produce resonance, and spin direction deflects in the case where radio-frequency pulse acts on, in aligned transfer,
I.e. there occurs electromagnetic induction phenomenon；After radio-frequency pulse disappears, these hydrogen atoms are all restored to original state, in recovery process
In, release energy and change spin direction, the signal produced at this time to these hydrogen atoms samples, and is then gathered using these
