Abstract

A digital radiographic detector system includes a number of DR detectors enclosed by a housing. A base section with wheels has attached thereto a vertical column with a height adjustable horizontal arm extending therefrom. The housing with DR detectors therein is attached to a distal end of the horizontal arm. The housing comprises a major surface made from a radiolucent material to allow the detectors to capture radiographic images via x-rays transmitted through the major surface of the housing. The housing is configured to support the plurality of DR detectors therewithin.

First claim

What is claimed is:

1. A digital radiographic detector system comprising:
a plurality of DR detectors each comprising a radiographic imaging array secured in a housing;
a base having a plurality of wheels attached thereto for rolling the system over a surface; and
a support attached to the base and to the detectors such that the detectors are supported in a preselected alignment,
wherein the housing of each detector comprises a radiolucent surface over the imaging array and at least one radiolucent edge.

2. The system of claim 1 , wherein the preselected alignment comprises a vertical alignment wherein the at least one radiolucent edge of each of the detector's housing are parallel.

3. The system of claim 2 , further comprising a separate DR detector mounted on a wall, wherein the parallel radiolucent housing edges are separated by a gap, the base is configured to be rolled into a position such that the separate DR detector mounted on the wall is positioned in the gap, and wherein the at least one radiolucent edge of each of the detector's housing overlaps the separate DR detector mounted on the wall.

4. The system of claim 3 , wherein the plurality of DR detectors and the separate detector mounted on the wall are each configured to wirelessly transmit captured radiographic image data.

5. A digital radiographic imaging system comprising:
an x-ray source; and
three DR detectors each comprising a radiographic imaging array secured in a housing, wherein the three detectors are fixed in position relative to each other,
wherein two of the detectors are fixed in a common plane and a third one of the detectors is fixed in a plane parallel to the common plane, the plane parallel to the common plane is closer to the x-ray source, and wherein the housing of the third one of the detectors comprises a radiolucent surface over the imaging array and two radiolucent edges that each overlap one of the at least two detectors fixed in the common plane.

6. A digital radiographic imaging system comprising:
an x-ray source; and
three DR detectors each comprising a radiographic imaging array secured in a housing, wherein the three detectors are fixed in position relative to each other,
wherein two of the detectors are fixed in a common plane and a third one of the detectors is fixed in a plane parallel to the common plane, the plane parallel to the common plane is further from the x-ray source, and wherein the housings of the two detectors each comprises a radiolucent surface over the imaging array and a radiolucent edge that overlaps the third one of the detectors.
