An x-ray detector, comprising:
- a plastic housing including a conductive coating and a groove in the plastic housing disposed along a perimeter of the plastic housing;
- a two-dimensional sensor array disposed within the plastic housing and configured to generate image data in response to incident x-rays;
- a front plate connected to the plastic housing, the front plate and the plastic housing forming an enclosure surrounding the two-dimensional sensor array;
- and
- a conductive gasket disposed in the groove of the plastic housing between the front plate and the plastic housing and electrically connected to the front plate and the conductive coating and sealing an interface between the front plate and the plastic housing;
- wherein the conductive coating and the front plate form at least part of an electromagnetic interference shield around the two-dimensional sensor array.
A method of forming an x-ray detector, comprising:
- providing a plastic housing including a groove in the plastic housing disposed along a perimeter of the plastic housing;
- applying a conductive coating to the plastic housing;
- attaching a two-dimensional sensor array configured to generate image data in response to incident x-rays to the plastic housing;
- forming an enclosure surrounding the two-dimensional sensor array using the plastic housing and a front plate, including placing a conductive gasket in the groove of the plastic housing between the front plate and the plastic housing;
- electrically connecting the front plate and the conductive coating and sealing an interface between the front plate and the plastic housing with the conductive gasket;
- and
- electrically connecting the two-dimensional sensor array to the conductive coating.
