Acoustic detection of microbubble resonance
(2009)Large numbers of acoustic signals from single lipid-shelled Definity (R) microbubbles have been measured using a calibrated microacoustic system and a two population response observed. Theoretical results based on the ... -
The acoustic signature of decaying resonant phospholipid microbubbles
(2013)Sub-capillary sized microbubbles offer improved techniques for diagnosis and therapy of vascular related disease using ultrasound. Their physical interaction with ultrasound remains an active research field that aims to ... -
The effect of resonance on transient microbubble response; Response; experimental and theoretical observations
(2012)Nonlinear microbubble oscillations can be exploited by signal processing to provide contrast enhancement in ultrasound imaging. High-speed optical investigations have established that microbubbles resonate in-vitro, but ... -
The fate of resonant and off-resonant microbubble signals in response toconsecutive imaging pulses
(2010)The study of single microbubble (MB) acoustics has relevance to signal andimage processing of ultrasound (US) contrast imaging. The aim of this work is tostudy the effect of consecutive pulses on MB response. RF backscatter ... -
A new theoretical model for cracked microbubbles
(2009)The response of the rigid shelled contrast agent biSphere® has been previously studied optically and acoustically over a range of mechanical index (MI). Free bubble models have been used to model the behaviour of rigid ...
