Abstract

Procédé et appareil à écho-impulsion ultrasonique amélioré s'appliquant notamment à des mesures de précision de compressibilité dans n'importe quelle matière de rétrodiffusion, notamment des tissus organiques. Le procédé utilise un transducteur classique ou un dispositif contenant un transducteur, lequel est déplacé transaxialement, comprimant ou déplaçant ainsi une région proximale d'un corps cible par de petits incréments connus. A chaque incrément, une impulsion est émise et une séquence d'échos (ligne A) est détectée à partir de régions situées dans la cible le long du chemin de déplacement des ultrasons ou du faisceau du transducteur. Les décalages temporels résultant au niveau des segments d'écho correspondant à des caractéristiques de la cible, corrigés en fonction des régions de vitesse d'ultrasons variables dans le chemin des ultrasons, fournissent des informations relatives et quantitatives sur les contraintes provoquées par les compressions. L'effort que le transducteur et le dispositif conteneur font subir est également déterminé et corrigé en fonction des profondeurs sur le chemin des ultrasons. Les valeurs appropriées d'effort sont divisées en les valeurs respectives de contrainte le long de chaque chemin afin de produire un élastogramme, ou un réseau de valeurs de compressibilité, de la cible.
