Abstract
A modular x-ray lens system for use in directing x-rays comprising a radiation source which generates x-rays and a lens system which directs the x-rays, wherein the x-ray lens system may be configured to focus x-rays to a focal point and vary the intensity of said focal point.
Claims30
An x-ray system for directing x-rays comprising:
- a lens system which directs said x-rays, wherein said lens system comprises at least one lens element comprising a housing with a generally enclosed interior, said interior of said housing lined with a Bragg x-ray diffraction and reflection layer and said housing does not reflect said x-rays, wherein said Bragg x-ray diffraction and reflection layer comprises a mosaic crystal comprising a curved cross section lengthwise and said mosaic crystal comprises a curved crystal plane with a differing radius from that of said curved cross section.
An x-ray system for direting x-rays comprising:
- a lens system which direct said x-rays, wherein said lens system comprises at least one lens element comprising a housing with a generally enclosed interior, said interior of said housing lined with a Bragg x-ray diffraction and reflection layer;
- wherein said lens system comprises a plurality of lens elements coupled along their symmetric axis and said coupled lens elements do not overlap one another in a direction perpendicular to their symmetric axis.
An x-ray system for directing x-rays comprising:
- a lens system which directs said x-rays, wherein said lens system comprises at least one lens element comprising a housing with a generally enclosed interior, said interior of said housing lined with a Bragg x-ray diffraction and reflection layer and said housing does not reflect said x-rays;
- and
- a ring-like apparatus comprising a filter medium coupled to a center of said ring-like apparatus, wherein said ring-like apparatus occludes a portion of said x-rays which are not incident upon said lens system and do not fall into a focusing region of said lens system, said filter medium filtering a portion of said x-rays which is directed to said focusing region.
An x-ray system for focusing x-rays comprising:
- a modular lens system comprising a plurality of lenses which collect said x-rays and focus said x-rays to a focal point, wherein x-ray focusing properties of said modular lens system can be varied by removing and adding said plurality of lenses or changing the properties of said plurality of lenses.
An x-ray lens system comprising:
- a plurality of lenses, each of said plurality of lenses comprising a housing comprising an inner surface lined with graphite,
- an x-ray filter proximate said plurality of lenses, and
- wherein said inner surfaces of said plurality of lenses in combination are formed to give said x-ray lens system an interior generally spherical surface.
An x-ray system for directing x-rays:
- a lens system which directs said x-rays, wherein said lens system comprises at least one lens element comprising a cylindrical housing comprising an interior, said interior of said cylindrical housing lined with a mosaic crystal, whereby said mosaic crystal acts as a Bragg or Laue lens to direct said x-rays, and
- a mask for occluding x-rays off axis to said lens system;
- and
- a filter for filtering x-rays substantially coaxial to said lens system and which are directed to a focusing region.
1 more element
An x-ray system for directing x-rays comprising
- a lens comprising a Bragg x-ray diffractive layer, wherein said directed x-rays are transmitted and diffracted through said lens;
- wherein said lens is constructed from a plurality of concentric rings of mosaic crystal forming a plurality of diffractive layers.
