The potential of Lung ultrasound (LUS) has become manifest in the light of the COVID-19 pandemic. Conventional ultrasound imaging is however not designed for lung assessment, which limits its applicability to subjective and qualitative interpretations of imaging patterns. New research directions have now emerged which tackle this limitation. This special issue reports on their most recent findings. Through numerical, experimental, and in-vivo studies, the research presented aims at understanding and modeling the physical phenomena at stake in ultrasound propagation, and at leveraging these phenomena to extract semi-quantitative and quantitative information relevant to estimate changes in lung structure.
