    摘要： A method for generating X-rays in an X-ray tube (10), comprises the steps of rotating an X-ray target (17) of a rotating anode (16), the X-ray target having a metal coated layer (23) thereon, of applying electron beams (18) emitted from a cathode (15) onto the metal coated layer (23) of the X-ray target, and of offsetting thermal deformation of the X-ray target (17) due to the application of said electron beams by deformation of the X-ray target (17) due to centrifugal force, thereby maintaining a position of the X-ray target (17) in a direction of the application of the electron beams, at a room temperature of the X-ray target, thus generating the X-rays.

    摘要翻译： 一种用于在X射线管（10）中产生X射线的方法，包括以下步骤：旋转阳极（16）的X射线靶（17），所述X射线靶具有金属涂层（23 ），将从阴极（15）发射的电子束（18）施加到X射线靶的金属涂层（23）上，并且由于应用而抵消X射线靶（17）的热变形 的所述电子束由于离心力而由X射线靶（17）的变形引起，从而在施加电子束的方向上保持X射线靶（17）的位置在室温 X射线靶，从而产生X射线。
