Abstract

A digital radiographic detector having a radiolucent cover and housing at one or more edges of the detector allows radiographic imaging using multiple detector arrangements with overlapping edges that do not obstruct radiographic images captured thereby.

Claims

1-20. -20. (canceled)

21. A digital radiographic detector system comprising:

a movable frame; and

at least two digital radiographic detectors secured to the movable frame in a common plane, wherein the at least two digital radiographic detectors are spaced apart by a preselected gap therebetween.

22. The detector system of claim 21, wherein the movable frame comprises wheels.

23. The detector system of claim 22, wherein the movable frame and the at least two radiographic detectors are configured to be moved adjacent to at least one other radiographic detector disposed in a second plane parallel to the common plane, wherein the at least one other detector is disposed in the preselected gap.

24. The detector system of claim 23, wherein the at least two digital radiographic detectors secured to the movable frame each comprise a housing having a radiolucent edge, wherein the radiolucent edges of the at least two detectors are parallel to each other.

25. The detector system of claim 23, wherein the at least two digital radiographic detectors overlap the at least one other radiographic detector disposed in the second plane.

26. A digital radiographic imaging system comprising:

an x-ray source; and

at least four digital detectors positioned to be simultaneously exposed by the x-ray source,

wherein at least one of the digital detectors is disposed in a first plane perpendicular to at least one x-ray emitted by the x-ray source, and wherein remaining ones of the at least four digital detectors are disposed in a second plane parallel to the plane perpendicular to said at least one x-ray.

27. The imaging system of claim 26, wherein all of the at least four digital detectors each overlap at least one other of the detectors or are overlapped by at least one other of the detectors.

28. The imaging system of claim 26, wherein said at least one of the digital detectors disposed in the first plane each comprises a housing having at least one radiolucent edge.

29. The imaging system of claim 28, wherein said remaining ones of the digital detectors disposed in the second plane each comprise a housing having four radiopaque edges.

30. A digital radiographic detector system comprising:

a movable frame;

at least two digital radiographic detectors secured to the movable frame in a common plane, the at least two digital radiographic detectors each comprising a housing having a radiolucent edge; and

at least one other radiographic detector disposed in a second plane parallel to the common plane,

wherein the at least two digital radiographic detectors are spaced apart by a preselected gap therebetween, the movable frame and the at least two radiographic detectors are configured to be moved adjacent to the at least one other detector, and wherein the at least two spaced apart digital radiographic detectors each comprise a device layer having an edge that overlaps a device layer in the at least one other radiographic detector disposed in the second plane.
