Tissue elasticity imaging is expected to be one of novel modalities for image diagnosis based on tissue characterization. However, it is basically difficult for conventional methods for tissue elasticity imaging to image anechoic region, since echo level is extremely low. Therefore, we proposed a new method for tissue elasticity imaging which is applicable to anechoic region. This method is simple and enables us to know a certain amount of tissue hardness information, but its image quality was insufficient. Therefore, in this paper, we attempt improving the image quality in anechoic region by correcting and interpolating a displacement profile iteratively. In addition, we confirm the validity of the proposed method by simulations and phantom experiments.
