    • 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 acoustic signature of decaying resonant phospholipid microbubbles 

      Thomas, D. H.; Butler, M.; Pelekasis, N.; Anderson, T.; Stride, E.; Sboros, V. (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 ...

    • Secondary Bjerknes forces between two bubbles and the phenomenon of acoustic streamers 

      Pelekasis, N. A.; Gaki, A.; Doinikov, A.; Tsamopoulos, J. A. (2004)
      The translational velocities of two spherical gas bubbles oscillating in water, which is irradiated by a high-intensity acoustic wave field, are calculated. The two bubbles are assumed to be located far enough apart so ...

    • Simulations of insonated contrast agents: Saturation and transient break-up 

      Tsigklifis, K.; Pelekasis, N. A. (2013)
      Under insonation contrast agents are known to perform nonlinear pulsations and deform statically, in the form of buckling, or dynamically via parametric mode excitation, and often exhibit jetting and break-up like bubbles ...
