Loss of echogenicity and onset of cavitation from echogenic liposomes: pulse repetition frequency independence.

Radhakrishnan K1, Haworth KJ2, Peng T3, McPherson DD3, Holland CK2.
Ultrasound in medicine & biology.Ultrasound Med Biol.2015 Jan;41(1):208-21. doi: 10.1016/j.ultrasmedbio.2014.08.021. Epub 2014 Nov 15.
Echogenic liposomes (ELIP) are being developed for the early detection and treatment of atherosclerotic lesions. An 80% loss of echogenicity of ELIP has been found to be concomitant with the onset of stable and inertial cavitation. The ultrasound pressure amplitude at which this occurs is weakly dep

The Influence of the Insonation Conditions of Pulsed Ultrasound on Microbubble Volumetric Oscillations (On the Mechanical Index and the Oscillation Characteristics)

宮本武司,吉澤晋,松本洋一郎
日本機械学会論文集Ｂ編 77(774), 264-273, 2011
… The influence of the insonation conditions of short-pulse and low-duty diagnostic ultrasound on the characteristics of microbubble volumetric oscillations in the initial bubble radius range from 0.2 to 2.0 micro meters has been numerically investigated by using a recent single bubble oscillation model. … The results show that increasing insonation center frequencies with the constant values of the mechanical index reduces the maximum values of both of the in-bubble temperatures and the bubble-emitted sound pressures; …

… However, neither precise mechanism of sonoporation nor optimum sequence of insonation has been clarified. … In this paper, effects of pre-trapping of micro bubbles to the target wall, which is carried out by pumping ultrasonic wave before insonation using high intensity ultrasonic wave, is evaluated by N-isopropylacrylamide (NIPA) gel flow channel. …
