Abstract: A rotating anode x-ray tube employing a generally cylindrical anode which is axially moveable relative to the cathode so that the focal spot traverses a spiral path as the anode rotates and moves axially. The axial displacement of the anode can be controlled by the temperature of the focal spot, i.e. by measuring the light emitted from the focal spot area.

Abstract: An X-ray tube anode target assembly (101) having a support shaft (107) connected to a pivot assembly (109) and a movable anode target (105) having a target surface (106) disposed at one end of the support shaft and a contact element (108) disposed at the opposite end of the support shaft. A first drive assembly (115) is operably arranged with respect to the support shaft to provide oscillatory motion to the anode target about a first axis substantially parallel to the support shaft and a drive cylinder (125) is operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly (127) is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder being further configured to provide a linear motion parallel to the first axis. The target surface is maintained at a substantially constant angle of impingement and maintains a substantially fixed distance from a cathode (103) during target motion.

Abstract: The present invention provides an x-ray source including an electron-generation chamber with an electron beam source that emits electrons and a target chamber with a support structure and a target positioned within the support structure. The emitted electrons travel in a direction substantially parallel to a longitudinal axis extending between the electron-generation chamber and the target chamber towards the target and bombard the target to generate x-rays. The target is movable, while being bombarded with electrons, with respect to the support structure in at least one direction perpendicular to a longitudinal axis.
