Figures & data
Figure 1 Variation of the transmitted ultrasound intensity, (I0 is the ultrasound intensity in the absence of bubbles) at 25°C, as a function of time, for PFH–containing microbubbles stabilized with a) DMPC alone and b) F-PC. The mean diameter of all the microbubbles investigated is ∼ 14µm. The half-lives are 5 and 70 min for the microbubbles with shells made of DMPC and F-PC, respectively.
Figure 2 Size distributions of microbubbles filled with N2 saturated with PFH and having a shell made of F-PC measured immediately after dilution of the initial foam, after 30 min and after 60 min, or a shell made of DMPC (inset) at 0 min, 5 min and 10 min.
