Abstract:
A method for testing an object (1), wherein a sectional image of the object is generated in at least a partial segment (3) of the object by means of an X-ray computer tomographer, the object (1) being clamped in a holding device within which at least a partial segment (3) is brought in a direction extending transversely to the segment into a beam path (S) between an X-ray source (10) and an X-ray detector (11) of the computer tomographer, the object (1) and the holding device (30) then being rotated in at least one angular region (.gamma.), relative to the X-ray source (10) with the X-ray detector (11) about a first axis (20) that extends through the partial segment (3) and the beam path (S), the partial segment (3) remaining in the beam path (S), the X-ray detector (11) recording a radiogram in specific angular increments, and a cross-sectional image through the partial segment (3) being reconstructed from these radiograms, wherein the object (1) is a receptacle (1) having a folded-seam connection (2) between a lid (5) or bottom (6) and a jacket (4), and, to generate a sectional image through this folded-seam connection (2) in the radial direction, the holding device (30) is rotated about the first axis (20); then generate at least one further sectional image through at least one further partial segment of the folded-seam connection (2), the receptacle (1) being rotated along a circumference thereof in the holding device (30) until the further partial segment of the folded-seam connection (2) is located in the beam path (S), and the holding device (30) and the receptacle (1) are then rotated about the first axis (20) again to generate an image.
