METHOD FOR SUPERPOSING PROJECTIVE IMAGES OF THREE-DIMENSIONAL STRUCTURES WITH A TWO-DIMENSIONAL X-RAY IMAGE

Verfahren zur Verarbeitung eines dreidimensionalen Bilddatensatzes mit zweidimensionalen Röntgenaufnahmen eines Röntgengerätes, unter Verwendung einer Zielfunktion. Medical imaging methods for processing a three-dimensional (3D) image data set with two-dimensional X-ray images from an X-ray machine using a target function. Methods can include providing a 3D image data set of at least one examination zone in which anatomical structures are present, segmenting the image data set to provide a 3D vascular structure model and a 3D bone structure model, recording a first two-dimensional (2D) X-ray image containing at least a portion of the vascular structure and at least a portion of the bone structure, recording a second 2D X-ray image of the examination zone at a different contrast agent concentration, and subtracting the first and second 2D X-ray images to generate a subtraction image. An optimum projective geometry may then be determined using a three-part target function based on the 3D image data and the 2D X-ray images.
