ABSTRACT:
The principles of nuclear magnetic resonance are employed to determine material properties of test subjects such as the constituent ratios of component elements making up the test subject and the rate of fluid change taking place in the test subject, in which analysis a plurality of magnetic resonance radiations from the test subject are generated by a plurality of series of 90 degree pulses of alternating magnetic field having different pause periods between adjacent pulses, and each measured value of the intensity of the plurality of magnetic resonance radiations is substituted into a mathematical relationship relating the intensity of the magnetic resonance radiation to a plurality of sources thereof respectively associated with the material properties, which relationship provides a set of simultaneous algebraic equations, that is solved to obtain the numerical values of the material properties.
