Comparison of PE identified LUS frames, where image (A) does not meet the clinical criteria needed for contouring PE and image (B) is the ideal case for PE segmentation. The presence of PE was defined as an anechoic space (in red) between the parietal pleura (lining the chest wall in orange and diaphragm in yellow) and visceral pleura (lining the lung surface in green) image B, along with the collapsed lung tissue (in green)
