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.

Claims

a housing attached to a distal end of the arm, the housing comprising a major surface made from a radiolucent material;

wherein the housing encloses and supports therewithin the plurality of DR detectors, and wherein the radiographic imaging array of the plurality of DR detectors each faces the housing major surface made from the radiolucent material.

2. The system of claim 1, further comprising:

a rotatable joint attached to the housing and to the arm to rotatably attach the housing to the arm, the rotatable joint configured to enable variable positioning of the housing into at least two positions, wherein a first position of the housing includes the major housing surface positioned in a vertical plane facing away from the column, and wherein a second position includes the major housing surface lying in a horizontal plane facing upward.

3. The system of claim 1, wherein the housing supports therewithin the plurality of DR detectors each in a plane parallel to one another, wherein the housing is configured to receive an additional DR detector and to secure the additional DR detector within the housing in a plane parallel to the planes of the plurality of DR detectors.

4. The system of claim 1, further comprising a wall hanger for hanging a grid thereon, the wall hanger configured to facilitate securing the hanging grid onto the DR imaging system when the DR imaging system is wheeled close to the wall hanger such that the housing contacts the hanging grid.

5. The system of claim 1, wherein at least one of the plurality of detectors comprises a first communication connector configured to receive and engage a corresponding second communication connector on an additional detector, and wherein the additional DR detector is configured to communicate detector identification information through the communicatively engaged first and second connectors.

6. The system of claim 5, wherein the plurality of detectors and the additional detector each comprise electronic wireless communication circuits, and wherein the additional DR detector is configured to communicate detector identification information wirelessly or through the communicatively engaged first and second connectors.

7. The system of claim 6, wherein the plurality of detectors and the additional detector are configured to communicate with only one controller external to the DR detector system, and wherein the one controller is configured to control power distribution to the detectors within the housing and to control data connections between the controller and the detectors within the housing.

8. The system of claim 1, further comprising:

a rotatable joint attached to the housing and to the arm to rotatably attach the housing to the arm, the rotatable joint configured to enable variable positioning of the housing into at least two positions, wherein a first position of the housing includes the major housing surface positioned in a vertical plane facing in a horizontal first direction, and wherein a second position includes the major housing surface revolved about an axis parallel to the column facing in a horizontal second direction perpendicular to the first direction.

9. The system of claim 1, further including a single external connector on the housing that includes channels for transmitting power to the detectors, data to and from the detectors, and control instructions to and from the plurality of DR detectors.

10. A digital radiographic detector system comprising:
