Background, Motivation and Objective Ultrasound shear wave imaging (SWI), in which elasticity is estimated by measuring wave velocity, has great potential for characteristic cancer diagnoses. On applying SWI, a tissue is compressed by diagnostic probe, which causes velocity dispersion in accordance with an acousto-elasticity theory. In this study, the effect of the degree of compression on the probability of errors was investigated. Furthermore, the effect of directional filtering (DF), which detects a wave with specific propagation direction among waves, on reducing errors was studied.
