X-RAY TUBE, X-RAY SYSTEM, AND METHOD FOR GENERATING X-RAYS |
摘要 |
According to an exemplary embodiment an x-ray tube comprises a cathode, rotable disc anode, and a focal spot modulating unit, wherein the cathode is adapted to emit an electron beam, and wherein the focal spot modulating unit is adapted to modulate the electron beam in such a way that an intensity distribution of the electron beam on a focal spot on the anode is asymmetric such that the intensity of the electron beam on the focal spot is higher at the front of the focal spot with respect to the rotation direction.
