Abstract
A method for providing a 3D image data record of a physiological object with a metal object therein is proposed. To enable an image of the metal object in the physiological object, for instance a biopsy needle in a human patient to be recorded as a 3D image in this patient, two 2D x-ray images of the patient are obtained with the needle with the aid of a biplane x-ray system, and back projection allows a 3D image data record to be generated, which is then subject to a filtering with a gray-scale value window. After filtering, information relating to the position and shape of the metal object in space is obtained. The thus obtained first 3D image data record can be combined with another 3D image data record, in particular with a 3D image data record of the patient without the metal object obtained with the same biplane x-ray system.
