Fig. 1From: Effects of sub-atmospheric pressure and dissolved oxygen concentration on lesions generated in ex vivo tissues by high intensity focused ultrasoundBroadband noise during HIFU exposure: a atmospheric pressure, b sub-atmospheric pressure. The black solid line was the baseline detected without HIFU exposure. The red, blue and purple solid lines represent the broadband noise signal at the DOC of 2.0Â mg/L, 1.5Â mg/L and 1.0Â mg/L, respectivelyBack to article page
