Abstract
Some embodiments include an x-ray detector, comprising: a plastic housing; a two-dimensional sensor array disposed in a 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 printed circuit board mounted to the plastic housing at a plurality of mount points, wherein a centroid of the printed circuit board is closer to a center of the plastic housing than a centroid of the mount points.
Claims21
An x-ray detector, comprising:
- a 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 printed circuit board mounted to the plastic housing at a plurality of mount points;
- wherein a centroid of the printed circuit board is closer to a center of the plastic housing than a centroid of the mount points.
A method of forming an x-ray detector, comprising:
- providing a plastic housing;
- attaching a two-dimensional sensor array configured to generate image data in response to incident x-rays to the plastic housing;
- attaching a printed circuit board to the plastic housing at a plurality of mount points where a centroid of the printed circuit board is closer to a center of the plastic housing than a centroid of the mount points;
- and
- forming an enclosure surrounding the two-dimensional sensor array using the plastic housing and a front plate.
An x-ray detector, comprising:
- a plastic housing including a conductive coating;
- a flexible 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 flexible two-dimensional sensor array;
- an electromagnetic interference shield around the flexible two-dimensional sensor array;
- and
- a printed circuit board mounted to the plastic housing at a plurality of mount points;
- wherein:
- a centroid of the printed circuit board is closer to a center of the plastic housing than a centroid of the mount points;
- the conductive coating and the front plate are at least part of the electromagnetic interference shield;
- and
- a first dimension of the printed circuit board along an axis including the center of the plastic housing is less than a second dimension of the printed circuit board along a major axis of the printed circuit board.
