摘要

背景:肝脏中的声速(SoS)已被假定为非酒精性脂肪性肝病(NAFLD)分层的定量生物标志物。脂肪组织中的SoS低于健康肝脏。最近，我们提出了一种基于全合成孔径(FSA)数据的脉冲回波SoS重建方法。虽然现有方法采用延迟和或类似的波束形成操作，但在我们的方法中，我们应用延迟和时空滤波器，然后直接关联通道而不求和，从而避免了声速不匹配时的空间偏差。本文分析了该方法重建小鼠肝脏SoS的可行性。方法:我们

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
