X-ray apparatus with elements for automatically precisely positioning components relative to one another during assembly

An x-ray apparatus comprising a mounting member, an x-ray source carrier arranged at the mounting member, an x-ray source arranged therein at the mounting member and an x-ray detector carrier, an x-ray detector arranged at the detector carrier, said x-ray source requiring exact adjustment relative to the x-ray detector within an overall tolerance said x-ray source and the x-ray source carrier having interacting first source adjustment elements that automatically exactly adjust the x-ray source relative to the x-ray source carrier within a source tolerance during assembly of the x-ray source carrier, said x-ray detector and the x-ray detector carrier having interacting first detector adjustment elements that automatically exactly adjust the x-ray detector relative to the x-ray detector carrier within a detector tolerance during assembly of the x-ray detector, said x-ray source carrier and the mounting member having interacting second source carrier adjustment elements that automatically exactly adjust the x-ray source carrier relative to the mounting member within a source carrier tolerance when the x-ray source carrier is mounted at the mounting member, said x-ray detector carrier and the mounting member having interacting second detector carrier adjustment elements that automatically exactly adjust the x-ray detector carrier relative to the mounting member within a detector carrier tolerance when the x-ray detector carrier is mounted at the mounting member, and a sum of the source tolerance, the detector tolerance, the source carrier tolerance and the detector carrier tolerance being no larger than the overall tolerance.
