Also known as MRI, it's a technique that used resonance of nucleus ( it's also possible with electron resonance ) to acquire the reciprocal space of the spin density, and also relaxation properties. This is possible by using gradients in different direction. This gradients could affect the nuclear spin ( most of the time we consider proton from water, and less frequently another single spin system ) in different ways :

- changing the resonance frequency

- changing the frequency that is required to excite the nucleus

- changing the relative phases


Gradients could be used in two ways :

- apply gradients longer

- apply stronger gradients

Imagery is used for several purpose, like :

- routine medical imagery

- biomedical research imagery

- batteries

- other materials
