| Abstract(in English) | We made an imaging system which displays anisotropic property of the tissues in the form of the shear modulus by applying the low-frequency vibration via circular plate to the viscoelastic medium like biological soft tissues, and detecting its behavior ultrasonically. For measuring the amplitude and phase data tracing over the medium, we made a displaying system to incorparate the ultrasonic data obtained from a pair of scanners orthogonally placed. In estimating the shear modulus, a cylinder model representing the real behavior of the wave propagation is effective for isotropic cases. This time, we extended the model so that it could be applied for anisotropy medium. The validity of the model was evaluated by the trace of the medium and the dependence of the propagation velocity upon the direction. |
