Verfahren zur automatischen Bestimmung der relativen räumlichen Anordnung von Markern in einer Röntgen-CT-Vorrichtung

The invention relates to a method for automatically determining the relative spatial arrangement of at least three markers in an x-ray CT device, which has an x-ray source having a focus, an x-ray detector, and a manipulator, wherein the manipulator can move a test object in the intermediate space between the focus and the x-ray detector, wherein the markers consist of materials transparent to x-radiation and are arranged in a stationary manner in relation to the test object while the method is carried out, wherein the number of recordings made is so large that there are at least as many recordings of three of the markers as there are degrees of freedom of the manipulator.
