Abstract

Procédé d'affichage de la position d'un vaisseau sanguin et système d'imagerie ultrasonore. Le procédé consiste à : balayer un tissu cible dans un premier mode de balayage pour déterminer la position d'un vaisseau sanguin dans le tissu cible; balayer le tissu cible dans un second mode de balayage pour acquérir une première image ultrasonore correspondant au tissu cible, le nombre de trames de balayage correspondant au second mode de balayage étant supérieur au nombre de trames de balayage correspondant au premier mode de balayage; et afficher la position du vaisseau sanguin sur la première image ultrasonore. Lorsque la position d'un vaisseau sanguin est en cours de détermination, il n'est pas nécessaire de régler un dispositif d'imagerie ultrasonore, et la position du vaisseau sanguin est directement déterminée dans le cadre d'un processus d'imagerie ultrasonore, ce qui permet d'améliorer efficacement la rapidité de détermination de la position d'un vaisseau sanguin et d'améliorer ainsi efficacement l'efficacité de l'imagerie ultrasonore.
