Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Bestimmung der optimalen Bildrekonstruktionsphase für sich quasiperiodisch bewegende Objekte, insbesondere hinsichtlich der Computertomographie (CT) des Herzens. Eine Aufgabe der vorliegenden Erfindung ist es, im Hinblick auf Reduktion der Bewegungsartefakte eine automatische Bestimmung der optimalen Bildrekonstruktionsphase zu ermöglichen. Diese Aufgabe wird durch ein Verfahren zur Darstellung eines sich quasiperiodisch bewegenden Objektes mit Hilfe eines Bildauf nahmesyεtems (1), insbesondere eines Computertomographen, unter Verwendung einer phasenkorrelierten Rekonstruktionstechnik gelöst, bei dem eine optimale Bildrekonstruktionsphase unter Verwendung einer Bewegungsfunktion (8) des Objektes bestimmt wird.
