Multi-maximum x-ray spectrum systems and multi-layer imaging systems
Some embodiments include an x-ray system, comprising: a housing; a plurality of overlapping imaging layers disposed in the housing, each imaging layer configured to generate an image in response to a corresponding incident x-ray beam; and a plurality of x-ray markers attached to the housing and disposed to affect the incident x-ray beam for each of the imaging layers.
1. An x-ray imaging system, comprising:
a housing;
a plurality of overlapping imaging layers disposed in the housing, each imaging layer configured to generate an image in response to a corresponding incident x-ray beam; and
a plurality of x-ray markers attached to the housing and disposed to affect the incident x-ray beam for each of the imaging layers.
2. The x-ray system of claim 1 , wherein
each of the imaging layers includes a rectangular sensor array including four quadrants;
the markers are disposed relative to the imaging layers such that shadows of the markers appear in at least two quadrants of the resulting images.
3. The x-ray system of claim 1 , wherein positions of the markers are fixed relative to the imaging layers.
4. The x-ray system of claim 1 , wherein positions of the markers are movable relative to the imaging layers.
5. The x-ray system of claim 1 , wherein positions of the markers are movable relative to the imaging layers such that the markers may be moved to not cast an x-ray shadow on one or more of the imaging layers.
6. The x-ray system of claim 1 , wherein at least one of the markers has a spherical shape.
7. The x-ray system of claim 1 , wherein at least one of the markers has a cylindrical shape.
8. The x-ray system of claim 7 , wherein a major axis of the at least one of the markers is parallel to a major axis of the imaging layers.
9. The x-ray system of claim 1 , wherein at least one of the markers has a shape or orientation different from another marker of the markers.
10. The x-ray system of claim 1 , wherein at least one of the markers has a disk shape.
11. The x-ray system of claim 1 , wherein at least one of the markers has a rectangular prism shape with a side parallel to an imaging surface of the imaging layers.
12. The x-ray system of claim 1 , wherein at least one of the markers includes a sheet disposed parallel to an imaging surface of the imaging layers.
13. The x-ray system of claim 1 , wherein at least one of the markers includes an L shape with legs of the L shape being aligned to X and Y axes of an imaging surface of the imaging layers.
14. The x-ray system of claim 1 , wherein at least one of the markers includes a material having a k-edge in the x-ray spectrum of the x-ray beam.
15. The x-ray system of claim 1 , wherein at least one of the markers is disposed within the housing.
16. The x-ray system of claim 1 , wherein at least one of the markers is disposed outside of the housing.
17. An x-ray system, comprising:
means for housing imaging layers;
a plurality of means for generate an image in response to a corresponding incident x-ray beam, disposed in the means for housing imaging layers; and
a plurality of means for affecting the incident x-ray beam for each of the imaging layers.
18. The x-ray system of claim 17 , further comprising:
means for moving the means for affecting the incident x-ray beam for each of the imaging layers.
