L'appareil d'imagerie ultrasonore comprend également : une unité de déclenchement d'opération rapide (13) pour générer, sur la base d'un événement, une commande de balayage pour effectuer une imagerie 3D/4D basée sur des données ultrasonores bidimensionnelles, l'événement comprenant un mode d'imagerie 3D/4D sélectionné par l'utilisateur pour un objet cible ; et une unité de traitement (14) pour configurer, sur la base de la commande de balayage, un paramètre de balayage et pour générer, sur la base de données ultrasonores balayées par la sonde ultrasonore (12) et du paramètre de balayage, une image 3D/4D. L'unité de déclenchement d'opération rapide (13) génère la commande de balayage pour effectuer l'imagerie 3D/4D. L'unité de traitement (14) configure automatiquement, sur la base de la commande de balayage, le paramètre de balayage et génère automatiquement, sur la base des données ultrasonores balayées par la sonde ultrasonore (12) et du paramètre de balayage, l'image 3D/4D. Une opération à touche unique de l'unité de déclenchement d'opération rapide (13) peut réaliser une imagerie 3D/4D. La présente invention est facile à utiliser, a une applicabilité élevée et offre une bonne expérience utilisateur.
