  The essential feature of the method is the employment of Elasto-Magnetic
Resonance Spectroscopy (EMRS) for precise local measurements of the attenuation
of shear elastic waves introduced into a biological sample. Such a measurement
can be accomplished by combining the EMRS method with such methods, in which
collective dislocations of spins are induced by external physical factors, such
as variable electric field, strong magnetic field gradient or longitudinal
elastic wave. Theoretical bases of the method presented, related with the
external factors, are discussed in the present paper.
