    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.
