Abstract
A digital radiographic detector has a detector panel that forms digital image data according to radiation exposure energy. An enclosure houses the detector panel, formed from an electrically conductive material and having a base with an inner base surface and an outer base surface and having, along its perimeter, one or more side walls that extend orthogonally from the inner base surface. A base magnetic shield extends as a layer of nanocrystalline material across at least one of the inner base surface and the outer base surface. A cover is formed from a non-conductive material and has a cover magnetic shield of a layer of a metallic alloy bonded to an inner surface. A side wall magnetic shield extends along one or more surfaces of the one or more side walls, wherein the side wall magnetic shield has at least one of the nanocrystalline material or the metallic alloy.
