Summary:PROBLEM TO BE SOLVED: To image viscoelastic characteristics in a specimen by a simple method.SOLUTION: Stepwise pressurization in which, after pressure is instantaneously increased to a certain pressure value, the certain pressure value is kept for a certain time period is performed to measure the variation with time of strain distribution in the specimen and to calculate a stress from strain distribution at a saturation measurement time when the effect of the viscosity of a viscoelasticity measurement reference layer is saturated, thereby evaluating the modulus of elasticity and the coefficient of viscosity of a body tissue.
