Ultrasound image of the dome of the diaphragm in brightness-mode (B-mode; left panel) and motion-mode (M-mode; right panel). As the diaphragm contracts, the dome moves towards the ultrasound probe. The larger the caudal displacement of the diaphragm, the greater the diaphragmatic contribution to tidal breathing.
