Abstract

MRI is a method which locates NMR（nuclear magnetic resonance）signal and creates an image. The method of the positioning is different from that of CT imaging.<br>Transmission and receive coils are used for handling electromagnetic wave in MRI. And 3-dimensionally independent three coils for application of gradient are equipped. One of the three coils is for slice selection of a patient, and the rest 2 coils are for locating signal on the 2-dimensional slice. This review explains the principle of image formation in MRI.
