Abstract
In an exemplary embodiment, a portion of the tube vacuum envelope is disposed between the rotor and stator of the anode drive motor. Taking into account the required high voltage safety, hitherto concessions as to the anode drive had to be made. The disclosure provides an improvement in this regard in that the anode and stator are connected to the same potential until a desired rotational frequency is attained. Only then, subsequent to disconnection of the drive voltage, is the radiography voltage applied for the necessary exposure period. If necessary, subsequently a braking voltage, or again a drive voltage, respectively, can be applied to the stator. Methods and installations in which, in accordance with the disclosure, the drive of the rotary anode is intensified, are, in particular, suited for utilization in medical x-ray diagnostics, mainly computer tomography.
