The technology of magnetic resonance imaging makes use of the spin attribute of atomic nucleus in patient's body or sample, and is in possession of many unique advantages. So it has been playing the increasingly important part in modern medical treatment and the advanced brain function research. In the article, from the viewpoint of physics, the precondition of imaging, the basic principle and the imaging steps of this technology are in detailed introduced. In addition, both advantages and disadvantages of magnetic resonance imaging are given.
