A unique distinction between surfactant stabilized ultrasound contrast agent ST68 and water (or tissue), is the enhanced ability of the agent to generate non-linear frequencies such as sub-harmonics (f 0 /2), higher harmonics (2f 0 ,3f 0 ,4f 0 ,...), and ultraharmonics (3f 0 /2,5f 0 /2,7f 0 /2,...), when insonated with fundamental frequency f...
Environmental influences on the new surfactant-stabilized bubbles, ST68, were investigated. We have developed a new surfactant-based contrast agent ST68, which is prepared by insonating buffered mixtures of Span 60 and Tween 80 in the presence of either air, PFC, or SF 6 gas. The effect of dilution, shear, and sonication on size distribution of ST68 showed that PFC-containing bubbles (ST68-PFC)...
