Abstract

A digital radiographic detector includes a planar multilayer core having a two-dimensional array of photo-sensitive cells. An enclosure comprises first and second shells connected together using a rail configured to be secured to at least one of the first and second shells. The rail is attached to at least one of the shells using screws.

First claim

The invention claimed is:

1 . A digital radiographic detector comprising:
two covers configured to form an enclosure, each of the covers comprising sidewall portions; radiographic image receptor pixels disposed between the covers; a plurality of rails extending along the sidewall portions; and a plurality of screws each extending through at least one of the covers and into the rail, for securing together the rail and said at least one of the covers.

2 . The detector of claim 1 , further comprising a plurality of bumpers extending along the sidewall portions and on an outside surface thereof, the bumpers each covering at least a part of the sidewall portions of each of the covers.

3 . The detector of claim 2 , wherein the plurality of rails are each disposed along the outside surface of the sidewall portions.

4 . The detector of claim 2 , wherein the two covers comprise a top cover and a bottom cover, the detector configured to capture a radiographic image when the top cover is facing a radiographic energy source.

5 . The detector of claim 4 , wherein the top and bottom covers each comprise a rectangular shape having flanged edges on each of four sides thereof.

6 . The detector of claim 5 , wherein the screws each extend through the flanged edges of both the top and bottom covers.

7 . The detector of claim 5 , wherein at least two of the bumpers overlap along one of the sidewall portions.

8 . The detector of claim 2 , wherein at least some of the bumpers comprise an L shape for extending around a corner of the detector.

9 . The detector of claim 8 , further comprising a flexible seal disposed between the flanged edges of the top and bottom covers.

10 . The detector of claim 9 , wherein the flexible seal comprises a gasket.

11 . The detector of claim 1 , wherein one of the two covers comprises a sidewall portion having a greater height than the sidewall portion of the other cover.

12 . The detector of claim 1 , wherein the rail comprises one of aluminum, magnesium, a polymer, carbon fiber, or steel.

13 . An enclosure for a digital radiographic detector, the enclosure comprising:
a first shell and a second shell configured to be fastened together to form the enclosure, the first shell and the second shell each comprising a sidewall portion having a height; a plurality of linear rigid rails each extending along one of the sidewall portions; and a plurality of screws each extending through at least one of the shells and into one of the rails.

14 . The enclosure of claim 13 , further comprising a plurality of bumpers extending along an outside surface of the sidewall portions of the top and bottom shells.

15 . The enclosure of claim 14 , wherein the sidewall portion of the first shell comprises a height greater than the sidewall portion of the second shell.

16 . The enclosure of claim 15 , wherein the plurality of rails are each disposed along an outside surface of the sidewall portion of the first shell.

17 . The enclosure of claim 16 , wherein the first and second shells each comprise a rectangular shape having flanged edges facing each other on each of four sides thereof.

18 . The enclosure of claim 17 , wherein the plurality of screws each extend through the flanged edges facing each other and into one of the rails.

19 . The enclosure of claim 17 , wherein the plurality of bumpers each comprise an L shape for extending around a corner of the enclosure.

20 . The enclosure of claim 17 , further comprising a gasket between the flanged edges facing each other.
