Study on the effects of motion on an estimation method of average speed of sound

Abstract In the image reconstruction of ultrasound B-mode images, an average speed of sound (SoS) in living tissue is assumed to be a constant value. However, the assumed value may be different with the true values because the SoS varies depending on the properties of the tissue. The error between the true and assumed SoS causes degradation of ultrasound B-mode images. We have proposed a method for estimating an average SoS distribution. In this study, we conducted numerical simulations and evaluated the effects of motion on the average SoS estimation method. Furthermore, we conducted phantom experiments. In both the numerical simulation and phantom experiment, when a B-mode image was reconstructed using the estimated average SoS distribution, the contrast value was improved regardless of the motions.
