Abstract

Die Erfindung betrifft ein Verfahren für die Computertomographie, nach dem zur Abtastung eines Objekts mit einem von einem Fokus ausgehenden konusförmigen Strahlenbündel und mit einem mehrere Zeilen von Detektorelementen aufweisenden Detektorsystem zum Detektieren des Strahlenbündels der Fokus ohne Relativbewegung zwischen Untersuchungsobjekt und Fokus in Richtung der Systemachse auf einer Fokusbahn um eine Systemachse bewegt wird, wobei das Detektorsystem der empfangenen Strahlung entsprechende Messdaten liefert und wobei die Länge der Fokusbahn wenigstens gleich der Länge eines Teilumlaufintervalls ist, dessen Länge zur vollständigen Rekonstruktion eines CT-Bildes ausreicht. Dabei werden aus aus einem Teilumlaufintervall stammenden Messdaten Rohbilder berechnet, deren Bildebenen relativ zu einer die Fokusbahn enthaltenden Mittelebene geneigt sind, und mehrere Rohbilder zu einem resultierenden CT-Bild zusammen gefasst.
