Abstract
Background: Speed-of-sound (SoS) in the liver has been postulated as a quantitative biomarker for stratification of non-alcoholic faty liver disease (NAFLD). SoS in adipose tissue is lower than in healthy liver. Recently, we have proposed a pulse-echo SoS reconstruction method based on full synthetic aperture (FSA) data. While existing methods apply a delay-and-sum or similar beamforming operation, in our method we apply delays and a spatio-temporal filter and then correlate channels directly without summing, thus avoiding spatial biases when the sound speed is mismatched. Here we analyze the feasibility of this method to reconstruct SoS in murine liver. Methods: We
