    • Acoustic detection of microbubble resonance 

      Thomas, D. H.; Looney, P.; Steel, R.; Pelekasis, N.; McDicken, W. N.; Anderson, T.; Sboros, V. (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 effect of resonance on transient microbubble response; Response; experimental and theoretical observations 

      Thomas, D. H.; Butler, M.; Looney, P.; Pelekasis, N.; Sboros, V. (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 

      Thomas, D. H.; Looney, P.; Butler, M.; Anderson, T.; McDicken, W. N.; Sboros, V.; Pelekasis, N. (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 

      Looney, P.; Thomas, D.; Steel, R.; Anderson, T.; Pelekasis, N.; Sboros, V. (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 ...
