X-ray tube target having enhanced thermal performance and method of making same

摘要

An x-ray tube includes a frame enclosing a high vacuum, a cathode positioned within the enclosure, and a target assembly. The target assembly includes a target cap, a focal track material positioned on the target cap to receive electrons from the cathode, and a foam material positioned within a cavity of the target cap and positioned proximate the focal track. The x-ray tube also includes a bearing assembly attached to the frame and configured to support the target assembly.
