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.
