Patent ID: 8128564

Claim:
A method for imaging a shear modulus, the method comprising: generating an elastic wave inside an object to be measured, wherein the elastic wave being a shear wave and wherein the elastic wave is generated by a shear wave generator or a supersonic generator; measuring the elastic wave ongoing inside the object to be measured, wherein the elastic wave is measured by MRI equipment or a supersonic measurement device; calculating a shear modulus of the inside of the object to be measured, based on a value obtained by differentiating the measured elastic wave one time, wherein the shear modulus is calculated by a controller using the measured elastic wave, and wherein the calculating of the shear modulus includes: calculating an irrotational component and a solenoidal component of a stress vector from the measured elastic wave; and calculating the shear modulus of the inside of the object to be measured, by using the calculated irrotational component, the calculated solenoidal component, and the value obtained by differentiating the measured elastic wave one time; and imaging the calculated shear modulus in the inside of the object, wherein the inside of the object is displayed by a display unit.
