Spatial representation method for area of investigation object, involves adjusting X-ray depending on area to be examined, so that beam limiting surface encloses examined area

摘要

The method involves determining multiple two-dimensional projection data records, identified by per projection direction. A projection data record is obtained from an X-ray (X) penetrating the investigation object (U), which has an abrasive medium axle (Sx) extended in projection direction, and is limited by a beam limiting surface. The X-ray is so adjusted depending on the area, which is to be examined, so that the beam limiting surface encloses the area (B), which is to be examined. An independent claim is also included for a device for spatial representation of an area to be examined, of an investigation object, which has an X-ray emitter for generating X-ray.
