1. A digital radiographic detector comprising:
- a housing comprising a top side, a bottom side substantially parallel to the top side, and a plurality of edges extending between a periphery of the top side and a periphery of the bottom side to form an interior volume of the housing; and
a multilayer imaging structure within the interior volume of the housing, the multilayer imaging structure comprising a substantially planar imaging side configured to face the top side of the housing and to face an external radiographic energy source emitting radiographic energy toward the top side of the housing,wherein the top side of the housing comprises a radiolucent material, at least one of the plurality of edges of the housing is made from a radiolucent material, and wherein at least one of the plurality of edges of the housing is made from a radiopaque material.

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.
