Abstract
This invention relates to a method of obtaining information of a specified or target area of a living body near its skin surface by the application of a nuclear magnetic resonance phenomenon (NMR). This invention comprises a static magnetic field generator for generating a static magnetic field H.sub.0, a radio-frequency magnetic field generator for generating a radio-frequency magnetic field H.sub.1 perpendicular to said static magnetic field H.sub.0 and having a nuclear magnetic resonance frequency f.sub.0, and means disposed in close proximity to said target area for focusing one or both of said magnetic fields thereon, and relates to a method of obtaining, with a high signal to noise (SN) ratio and with ease, information of a specified area of a living body from the outside or inside of the body.
