Claim:
1. A method for measuring an object, said method comprising: providing a coordinate measuring device having an x-ray detector, an x-ray sensor system with an x-ray source, and a rotatable table, having a rotation axis, arranged between the x-ray source and the x-ray detector; arranging the object and a calibration body on the table; rotating the table about the rotation axis; imaging, by tomography, the object and the calibration body during the rotating step; using the calibration body to determine a position of the rotation axis relative to at least one of the x-ray source and the x-ray detector during the imaging; mathematically correcting the determined position; and factoring into a reconstruction algorithm, a position of the rotation axis that deviates from a nominal position.
