Abstract

L'invention concerne les dispositifs d'échographie. Outre les éléments classiques, un dispositif d'échographie comprend un dispositif de traitement 53 qui effectue une déconvolution en temps réel sur les signaux d'écho fournis par la sonde 59, afin de tenir compte de la largeur finie du faisceau d'exploration, et d'éviter que cette largeur entraîne une diminution de la résolution Application à l'échographie médicale.
