description The invention relates to a method for controlling an X-ray tube (12). The X-ray tube includes at least one grid electrode (18) arranged between an anode electrode (14) and a cathode electrode (16). In an embodiment, the method includes focusing, via a focusing unit (24), a flow of electrons (26) from the cathode electrode (16) to the anode electrode (14); applying in a first switching state, a first electrical grid potential to the at least one grid electrode via a switching unit (28), to pinch off the flow of electrons (26) between the anode electrode (14) and the cathode electrode (16); 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 (26), at least the second electrical grid potential being provided by the focusing unit (24). 本发明涉及一种用于控制X射线管(12)的方法，所述X射线管具有在阳极电极(14)与阴极电极(16)之间设置的至少一个栅电极(18)，其中借助于聚焦单元(24)聚焦从所述阴极电极(16)至所述阳极电极(14)的电子流(26)，以及借助于开关单元(28)在第一开关状态中以用于夹断所述阳极电极(14)与所述阴极电极(16)之间的电子流(26)的第一栅电势并且在第二开关状态中以释放所述
