Abstract: In a method and a device for setting the focal spot position of an X-ray tube the focal spot position is regulated as a controlled variable by a closed loop regulation circuit. A deflector deflects the electron beam of the X-ray tube depending on a deflection signal, a deflection closed loop regulator generates the deflection signal depending on a focal spot position signal. A measurement arrangement measures a focal spot position signal. The deflector, the deflection closed loop regulator and the measurement arrangement form a closed loop regulation circuit with the focal spot position as the controlled variable and with the deflection signal as the control parameter.

Abstract: An apparatus for generating x-rays has a structural unit which contains an x-ray tube, a digital control, regulation and storage unit for operating the x-ray tube, and all other components associated with, and supporting, operation of the x-ray tube. All of the components in the structural unit are connected to the digital control, regulation and storage unit. The apparatus also includes a peripheral device having a process computer. The digital control, regulation and storage unit has an interface to the process computer, which forms a single interface to the process computer for all of the components of the structural unit.
