ABSTRACT:
A method for localizing a target (e.g., a tumor) in an object (e.g. human tissue) by scanning the object with an X-ray beam. The X-ray beam is translated and simultaneously rotated during the scan, the translatory and rotational movements being connected in such a way that the shadow image of the target is kept on the surface of a detector during the scan. In this way it is possible to measure the translation d of that image during the scan. From the translation in combination with the translation D and the rotation during the scan, the height of the target2above the detector surface 10 may be calculated. In this way only one scan is needed.
