L'appareil comprend au moins un capteur de position disposé sur un côté d'une sonde ultrasonore afin de capter une position de déplacement de la sonde ultrasonore. Une unité de détection de position reçoit un signal de position provenant du capteur et détecte la direction et l'amplitude du déplacement de la sonde ultrasonore sous forme de données de position selon le signal de position. Une unité de traitement graphique reçoit les données de position et les données d'image bidimensionnelle, combine les données d'image bidimensionnelle selon les données de position de la sonde ultrasonore, et affiche le résultat combiné sous forme d'une image tridimensionnelle.
