Abstract: An X-ray tube anode target assembly having a support shaft connected to a pivot assembly and a movable anode target surface disposed at one end of the support shaft. A first drive assembly 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 drive cylinder operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder having a cam portion to provide linear motion to the support shaft 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 during target motion.

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.

Abstract: A high flux X-ray tube anode target assembly (101). The assembly includes a support shaft (107) connected to a pivot assembly (109). The assembly further includes a movable anode target (105) having a target surface (106) disposed at one end of the support shaft. The target surface includes a single radius of curvature. The radius of curvature extends from a pivot point (110). The assembly also includes a drive member (119) operably arranged with respect to the support shaft to provide motion to the anode target. The assembly is configured to maintain a substantially fixed distance between the pivot point and the target surface.
