Fig. 10.

Representative optical images from high-speed microscopy showing filtered Definity bubble activity during the first burst of the 0.102 ms pulsing scheme for different sonication pressures and channel diameters. Individual frames are delineated by vertical black lines and red shaded frames indicate frames acquired during ultrasound exposure. Dashed blue lines in the first row indicate the boundary of the channel diameter. Scale bars on the bottom row represent 50 µm.
