X-ray imaging method

An X-ray image processing device comprising a first imaging device with an X-ray source and an X-ray image pick-up device which are adjustable in relation to an object to be examined in order to form a series of two-dimensional X-ray images where the object to be examined is projected onto the image pick-up device from different perspectives, and also including means for storing the X-ray images and programmable image processing means which are programmed so that the following image processing operations are performed:

• b) extracting a relevant structure of the object to be examined from a three-dimensional image of the same object to be examined which has been formed by a second imaging device,
• c) calculating synthetic projection images of the extracted structure, the structure being projected with the same geometrical parameters as used for the relevant structure during the formation of the individual X-ray images,
• d) forming superposition images by superposing the synthetic projection images and the X-ray images formed from the same perspectives, and
• e) displaying the series of superposition images.
