Topics covered include theoretical models describing the effect of encapsulation on the acoustic response of contrast microbubbles, models describing the interaction of contrast microbubbles with boundaries such as walls of experimental containers and blood vessels, ultrasound imaging techniques based on using microbubble contrast agents, and the phenomenon of sonoporation which is believed to open great possibilities for targeted drug delivery by means of contrast microbubbles. The chapter reviews recent results obtained in these areas.

L'utilisation de microbulles spécifiques reconnaissant leurs cibles permet de détecter de façon sensible les sites pathologiques ciblés (e.g. tumeurs). Le but de cette analyse est de fournir une base pour des investigations de réponse acoustique des agents de contraste ciblés qui oscillent près d'une paroi imitant la paroi vasculaire. Nous proposons plus particulièrement d'utiliser un modèle de la dynamique de la bulle qui tient compte du phénomène acoustique « compression only » (Marmottant,2005). Nous allons exploiter ce phénomène pour la détection de microbulles ciblées. À cet effet, nous avons résolu l'équation d'oscillation radiale pour une bulle encapsulée à proximité d'une paroi rigide et calculer l'écho diffusé par la microbulle. En utilisant différentes conditions d'excitation et pour des microbulles de tailles différentes. L'écho en pro...
