[0035] In a specific embodiment, taking into account the differences in X-ray tube models, two tube holders are provided on the support, and electrode conductive blocks are provided under the two tube holders. The wiring of the X-ray tube can be connected to the electrode conductive block of the tube holder on the left, or to the electrode conductive block of the tube holder on the right.
