Radiographic detector
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.
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.
