ABSTRACT:
In an MR imaging system and method using a surface coil, the intensity of a high frequency magnetic field providing a magnetic resonance signal of the maximum intensity for each of distances from a coil plane of the surface coil to planes to be imaged is determined and stored. When a distance from the coil plane of the surface coil to a desired plate to be imaged is set, data of the high frequency magnetic field stored corresponding to the set distance is read and the intensity of a high frequency magnetic field to be applied is determined on the basis of the read data.
