Medical ultrasound images are reconstructed with simplifying assumptions on wave propagation, with one of the most prominent assumptions being that the imaging medium is composed of a constant sound speed. When the assumption of a constant sound spee

Phase aberration is widely considered a major source of image degradation in medical pulse-echo ultrasound. Traditionally, near-field phase aberration correction techniques are unable to account for distributed aberrations due to a spatially-varying

We describe a method of distributed aberration correction from local sound speed estimates of tissue. In this case, compensated beamforming delays are computed using the eikonal equation to account for refracted paths of the ultrasound waves based on

Regularization has a critical impact on the performance of pulse-echo computed-tomography and is a key component of the speed-of-sound (SoS) reconstruction pipeline. We investigate SoS reconstruction accuracy through heterogeneous abdominal models. W

Objective. Speed of sound has previously been demonstrated to correlate with fat concentration in the liver. However, estimating speed of sound in the liver noninvasively can be biased by the speed of sound of the tissue layers overlying the liver. H
