Abstract
A method is for controlling an X-ray tube including at least one grid electrode arranged between an anode electrode and a cathode electrode. In an embodiment, the method includes focusing, via a focusing unit, a flow of electrons from the cathode electrode to the anode electrode; applying in a first switching state, a first electrical grid potential to the at least one grid electrode via a switching unit, to pinch off the flow of electrons between the anode electrode and the cathode electrode; and applying in a second switching state, a second electrical grid potential to the at least one grid electrode to enable the flow of electrons, at least the second electrical grid potential being provided by the focusing unit.
