Abstract

Procédé d'imagerie pour imager un objet à l'aide d'un dispositif d'imagerie comprenant une pluralité d'émetteurs aptes à émettre une onde élastique dans l'objet à imager et une pluralité de récepteurs aptes à recevoir une onde élastique provenant de l'objet à imager, ledit procédé comprenant les étapes de : - Déterminer (202) une première image de l'objet, à un premier niveau d'échantillonnage spatial, à partir d'une pluralité de signaux reçus chacun par l'un desdits récepteurs, - Définir (204), dans l'image, au moins une zone d'intérêt de l'objet à imager, - Déterminer (205) une seconde image de l'objet à partir d'une pluralité de signaux reçus chacun par l'un desdits récepteurs, la seconde image présentant, dans chaque zone d'intérêt, un second niveau d'échantillonnage spatial supérieur au premier niveau d'échantillonnage spatial.
