Abstract (en)
An anode (100) for a rotating anode X-ray tube is proposed, wherein the anode comprises an inner and/or an outer electron capturing element (120, 110). The inner and/or outer electron capturing elements are configured to capture electrons backscattered from the focal track of the anode. The outer electron capturing element (110) comprises an X-ray transparent member (114) such that X-rays can propagate in a radial direction through the X-ray transparent member. The inner electron capturing element (120) is closer to the axis of rotation (103) of the anode than the focal track, whereas the outer electron capturing element (110) has a larger distance to the axis of rotation (103) than the focal track.
