The method involves preparing a series of two-dimensional images (Di,....) with a first image generator; these are stored digitally. The object (3) under investigation is projected with different perspectives onto an x-ray image acquisition device. A three-dimensional image is produced from the same object with a second image generation device (2) and a relevant structure (122) extracted. Synthetic two-dimensional images are computed from the extracted structure, which is projected using the same geometric parameters as the real structure for generating individual x-ray images. Superposition images are generated by superimposing the synthetic projection images and the x-ray images produced with the same geometric parameters. |
