Abstract
A method and apparatus for a rotatable anode of an x-ray tube. The anode having an axis of rotation and includes a solid thin plate target having a substantially planar base surface extending from the axis of rotation to a periphery outlining the base surface, wherein the plate target includes target material for generating x-rays selected from a group of high-Z materials. The plate target has a thickness of about 1 mm or less. The method includes fabricating the thin plate target using silicon wafer processing technology using suitable materials for such technology in forming the plate target selected from the group of high-Z materials.
