Abstract
An X-ray tube target assembly and method of manufacturing same is provided. The X-ray tube target assembly comprises an injection molded target disk. The injection molded target disk includes an injection molded hub member and an injection molded outer member. The injection molded outer member comprises a plurality of injection molded outer member segments that are removably attached together and removably attached to the hub member to form the injection molded target disk. A target track is formed on an outer surface on one side of an outer periphery of the injection molded outer member.
Claims25
An X-ray tube target assembly comprising an injection molded target disk, wherein the injection molded target disk is fabricated from a refractory metal with a high atomic number.
An X-ray tube target assembly comprising:
- a substantially planar circular-shaped hub member with a central opening extending therethrough for attachment to a drive shaft;
- a substantially planar circular-shaped outer member removably attachable to an outer perimeter of the hub member;
- and
- a target track formed on an outer surface on one side of an outer periphery of the outer member.
An X-ray tube target assembly comprising:
- a substantially planar circular-shaped hub member with a central opening for attachment to a drive shaft;
- a plurality of substantially planar pie-shaped outer member segments removably attached together and removably attached to an outer perimeter of the hub member;
- and
- a target track formed on an outer surface on one side of an outer periphery of each of the plurality of outer member segments.
An X-ray tube target assembly comprising:
- an injection molded hub member with a central opening extending therethrough for attachment to a drive shaft;
- a plurality of injection molded outer member segments removably attachable together and removably attachable to an outer perimeter of the hub member;
- and
- a target track formed on an outer surface on one side of an outer periphery of the plurality of injection molded outer member segments.
A method of constructing an X-ray tube target assembly comprising:
- injection molding a substantially planar circular-shaped hub member with a central opening attachable to a drive shaft;
