    • 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 ...

    • Stability and simulations of insonated contrast agents-effect of the constitutive law 

      Pelekasis, N.; Efthimiu, K.; Tsiglifis, K. (2011)
      Under insonation contrast agents are known to exhibit dynamic patterns such as thresholding, compression only behavior, diffusion and deflation, shape deformation, buckling, jetting and break-up, not all of which can be ...

    • Tissue characterization: T1, t2 andt2* techniques 

      Carlsson M., Bidhult S. (2015)
      Noninvasive characterization of tissue has long been the unique domain of magnetic resonance imaging (MRI) when compared to other imaging modalities. Techniques for such typically emphasize one or more MR-based relaxation ...
