    • The present invention relates to the generation of multiple X-ray energies in an X-ray tube. In order to provide an X-ray tube capable of generating multiple-energy X-ray radiation with a minimized design setup and an improved switching capacity, a multiple-energy X-ray tube (10) comprises a cathode (12), an anode (14) and an electron-braking device (16). The anode comprises a target surface (18) provided for generating X-rays as a result of impinging electrons. The cathode is provided for emitting electrons (20, 144, 148, 150) towards the anode to impinge on the target surface of the anode. The electron-braking device is intermittently arrangeable in a pathway (22, 144, 148, 150) of the electrons from the cathode to the anode and configured to slow at least a part of the electrons of the electron beam such that the energy of re-emitted electrons is lower than the energy of arriving electrons.
    • 本发明涉及在X射线管中产生多个X射线能量。 为了提供能够以最小化的设计设计和改进的开关容量产生多能量X射线辐射的X射线管,多能X射线管(10)包括阴极(12),阳极 (14)和电子制动装置(16)。 阳极包括由于撞击电子而产生X射线的目标表面(18)。 提供阴极以朝向阳极发射电子(20,144,148,150)以撞击阳极的目标表面。 电子制动装置间歇地布置在从阴极到阳极的电子的通路(22,144,148,150)中,并且构造成减缓电子束的至少一部分电子,使得再次的能量 发射电子低于到达电子的能量。
