Noninvasive measurement of biological information by nuclear magnetic resonance: Measurement of relaxation time of a particular target by magnetic focusing method

In order to clarify the possibility of detecting cancer noninvasively by the measurement of the relaxation time, model experiments were performed by applying our proposed magnetic focusing method to conventional nuclear magnetic resonance (NMR) techniques. It was made clear that the relaxation time of a particular target was selectively estimated from the proximity of the target by this method.
