Figure 5 : Epipleural high frequency, three-dimensional (3D) ultrasound recordings of B-lines generated in the cortical layer of the porcine lung (upper panel).

Recordings were performed using 40 MHz (704b) transducer (lower left) of the Visualsonics Vevo 770 (Toronto, Canada) system (lower right). 3D ultrasound displays B-lines as multiple, vertical, “stalactite” - like structures trailing down from the pleural surface.
A video file (comet_composite- Desktop MP4 video) is accompanying this recording.
