Abstract
Systems, methods and apparatus are provided through which in some embodiments an X-Ray energy target includes composite material that varies spatially in thermal properties, and in some embodiments, the composite material varies spatially in strength properties. In some embodiments, the spatial variance is a continuum and in other embodiments, the spatial variance is a plurality of distinct portions.
Claims20
An X-ray target comprising:
- an X-ray target cap having an inner diameter and an outer diameter;
- and
- a composite graphite material operably coupled to the X-ray target cap,
- wherein the composite graphite material further comprises:
- a first region located in the vicinity of the outer diameter;
- and
- a second region located in the vicinity of the inner diameter
- having higher strength properties and lower heat conductive properties than the first region.
An X-ray target comprising:
- an X-ray target cap;
- and
- a composite graphite material operably coupled to the X-ray target cap,
- wherein the composite graphite material further comprises:
- a first region;
- and
- a second region having higher strength properties and lower heat conductive properties than the first region,
- wherein the first region is positioned further away from an inner diameter of the X-ray target cap than the second region.
An anode assembly of a computed tomography imaging system, the anode assembly comprising:
- an Xray target cap having an inner diameter and an outer diameter, and a focal track located on the outer diameter;
- and
- a composite graphite X-ray target operably coupled to the X-ray target cap comprising:
- a first region that is located in the vicinity of the inner diameter, and
- a second region having higher heat conductive properties and lower strength properties than the first region and second region being located in the vicinity of the outer diameter.
A method to grade a composite graphite X-ray target, the method comprising:
- creating a structure of thermal conductive graphite precursors that defines an outer perimeter of the X-ray target;
- placing a first layer of graphite precursors inside the structure;
- creating a second layer having lower thermal conductivity and higher strength graphite precursors than the first layer;
- pressing the composite graphite for a X-ray target;
- impregnating the composite graphite;
- graphitizing the composite graphite X-ray target;
- and
- purifying the composite graphite X-ray target.
