Local shear waves attenuation measurements by the MR methods
T. Klinkosz, C. J. Lewa
Abstract
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.
