Abstract

L'invention concerne un système d'imagerie diagnostique à ultrasons qui fonctionne en mode d'arrimage ou en mode portatif. Dans le mode de non arrimage, le système à ultrasons portatif est commandé au moyen de sa propre interface-utilisateur et de son écran plat. Dans le mode d'arrimage, le système à ultrasons portatif est raccordé à une station d'arrimage, l'écran plat du système portatif servant alors d'affichage au système raccordé. La station d'arrimage ressemble à un système à ultrasons sur chariot typique, équipé d'une unité centrale et d'un panneau de commande. Le système à ultrasons portatif fournit l'écran du système sur chariot lorsqu'il est raccordé.
