TUBE-DETECTOR ALIGNMENT USING LIGHT PROJECTIONS

摘要

The present invention relates to acquisition of medical image information of an object. In order to provide a user- friendly alignment of X-ray tube (18) and a detector (24), optionally combined with an anti-scatter grid, an alignment arrangement (200) is proposed, which comprises a tube attachment (26) with a first light projection device (28) and a detector attachment (34) with a second light projection device (36). The first and second light projection devices each generate a light pattern (30, 38) on a projection surface (32). The tube attachment (26) and the detector attachment (34) can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern (38) on the projection surface.
