The estimation of elasticity distribution in static elastography methods strongly depends on the shape of the transducer head. It is known that the insertion of a damper layer is effective in improving the spatial nonuniformity of an applied strain distribution. We have developed a new estimation method for assessing the effectiveness of this technique through structural analysis using the finite element method and acoustic analysis using the finite-difference time-domain method with multilayered tissues. From the results, the strain flatness inside the compressed tissue is markedly improved, especially near the tissue surface, by inserting a damper layer between the transducer and the tissue surface. The elasticity of an inclusion and the deeper region of a three-layer tissue are also adequately imaged.
