Abstract
L'invention concerne le domaine de la tomographie. Un appareil de tomographie à ordinateur du type translation et rotation utilise le signal d'électrocardiogramme d'un patient comme base de temps pour déclencher un mouvement de translation, afin que le faisceau atteigne le coeur au cours de la phase désirée du cycle cardiaque. Dans ce but, un détecteur 22 détecte un élément particulier du signal d'électrocardiogramme, et déclenche l'unité de commande 16 au bout d'un retard variable défini par le circuit de retard 24. Application à l'obtention de tomographies du coeur.
