- 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

- OBJECTIVE: To quantify cerebrovascular autoregulation as a function of gestational age (GA) and across the phases of the cardiac cycle.STUDY DESIGN: The present study is a hypothesis-generating re-analysis of previously published data. Premature infants (n=179) with a GA range of 23 to 33 weeks were

- 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; …
