A system (10) for precalibrating an X-ray tube (70) before installation in a CT scanner system aligns the focal spot (14) with the off-focal aperture, slice-defining aperture, and the detectors of the scanner, using an interface registration support (68) that receives and supports the X-ray tube (70) on a mount (82, 83, 85) that duplicates the mount of the scanner. The focal spot (14) is ajdusted with respect to a registration support (68), and the adjusted tube (70) and registration support (68) can then be mounted on the CT scanner without subsequent calibration. The precalibration can additionally test the tube (70).
