3P5-20 A Method to Reduce the Influence of Reflected Shear Waves on Shear Velocity Measurement(Poster Session)

Abstract

A method to reduce the error from reflected SW to measurement accuracy of SW velocity was proposed in this study. The scanning time delay in B-mode measurement causes a spatial frequency shift between the forward and backward SWs measured. Therefore, these SWs could be separated using a spatial frequency filter. The proposed method was verified using a soft tissue mimicking phantom. The reflected SW was filtered out from the observed SW and the SW velocities were determined.
