CONT

L'étude des vaisseaux, artères et veines, se fait en doppler, technique basée sur la réflexion des ultrasons sur les structures en mouvement (les globules rouges font ainsi office d'interfaces réfléchissantes), la fréquence de réception des ondes réfléchies sur le sang en mouvement étant dépendante de sa vitesse circulatoire [...] Il est aussi possible d'obtenir une imagerie avec codage couleurs en fonction du nombre et de l'énergie des globules rouges circulant (doppler énergie), cette technique étant plus sensible aux flux lents.
