Abstract
Official abstract text for this publication.
An X-ray generating device includes an electron beam generator configured to generate an electron beam; a target configured to generate X-rays in response to the electron beam incident on the target; an eccentric rotator configured to be eccentrically rotated to rotate the target while changing a position of the target; and a driver configured to rotationally drive the eccentric rotator.
First claim
Opening claim text (preview).
The invention claimed is: 1 . An X-ray generating device comprising: an electron beam generator configured to generate an electron beam; a target configured to generate X-rays in response to the electron beam incident on the target; at least one eccentric rotator configured to be eccentrically rotated to rotate the target while changing a position of the target; and a driver configured to rotationally drive the at least one eccentric rotator. 2 . The X-ray generating device according to claim 1 , wherein the at least one eccentric rotator comprises: a plurality of eccentric rotators; the plurality of eccentric rotators is away at an even angular interval in a circumference of the target; and the target is held by the plurality of eccentric rotators. 3 . The X-ray generating device according to claim 2 , wherein an axis of each of the plurality of eccentric rotators deviates by a common distance in a common direction from a geometric center of the plurality of eccentric rotators. 4 . The X-ray generating device according to claim 2 , wherein the plurality of eccentric rotators comprises three eccentric rotators. 5 . The X-ray generating device according to claim 2 , wherein a predetermined eccentric rotator in the plurality of eccentric rotators is configured to be rotationally driven by the driver; and other eccentric rotator(s) in the plurality of eccentric rotators is/are a follower rotator(s) configured to be rotated when the target is rotated by the predetermined eccentric rotator. 6 . The X-ray generating device according to claim 1 , wherein each of the at least one eccentric rotator includes an eccentric gear; and the target includes a gear meshing with the eccentric gear of each of the at least one eccentric rotator. 7 . The X-ray generating device according to claim 6 , wherein a number of teeth of each of the at least one eccentric gear is different from a number of teeth of the gear of the target. 8 . An X-ray imaging apparatus comprising: an X-ray generating device; and an X-ray detector configured to detect X-rays emitted from the X-ray generating device, wherein the X-ray generating device includes: an electron beam generator configured to generate an electron beam, a target configured to generate the X-rays in response to the electron beam incident on the target, an eccentric rotator configured to be eccentrically rotated to rotate the target while changing a position of the target, and a driver configured to rotationally drive the eccentric rotor.
