L’imagerie visuelle est \u00e9troitement li\u00e9e \u00e0 la propagation de la lumi\u00e8re dans un milieu transparent (l’air) et \u00e0 la r\u00e9flexion sur une surface opaque (la plupart des objets). En d’autres termes, nous ne pouvons voir que la surface des choses. Cependant, la structure de la terre ou du soleil est connue avec pr\u00e9cision. Comment sonder des objets aussi opaques ? Comment scanner le corps humain ? Quel est le lien entre la sismologie et l’imagerie m\u00e9dicale ?<\/p>\n

Cette conf\u00e9rence tentera de r\u00e9pondre \u00e0 ces questions, d\u00e9crira la physique des ondes \u00e0 l’aide d’une d\u00e9monstration, et pr\u00e9sentera enfin les derniers d\u00e9veloppements en mati\u00e8re d’imagerie m\u00e9dicale.<\/p>\n

L\u2019\u00e9v\u00e8nement sera en anglais et suivi d\u2019un \u00e9change avec le public ainsi que d\u2019une d\u00e9gustation de vins et de fromage.<\/em><\/p>\n

Stefan Catheline<\/strong> a obtenu son doctorat en physique (1998) \u00e0 l’Universit\u00e9 de Paris VII (Denis Diderot) pour ses travaux sur l’\u00e9lastographie transitoire. Ses recherches l’ont men\u00e9 de l’universit\u00e9 de Paris \u00e0 l’universit\u00e9 de Lyon, en France, en passant par l’universit\u00e9 de Californie, San Diego, aux \u00c9tats-Unis, et l’universit\u00e9 de Montevideo, en Uruguay. Ces voyages lui ont permis de se familiariser avec les ultrasons m\u00e9dicaux, l’acoustique sous-marine, la physique des ondes et la sismologie, entre autres. Il d\u00e9tient 12 brevets dans le domaine des ultrasons et de la sismologie et a \u00e9crit plus de 100 articles de recherche. Il a \u00e9t\u00e9 cofondateur de deux entreprises : Sensitive Object dans le domaine de l’interactivit\u00e9 acoustique et SEISME dans le domaine de l’\u00e9lastographie.<\/p>\n","protected":false},"excerpt":{"rendered":"
