Digital radiographic detector front cover bonding
A DR detector is formed from a housing with a cover attached to the housing. Shaped gaps formed in the housing and/or cover include a bonding agent or adhesive therein to fix the cover to the housing. Other attachment means such as screws or pins may be used instead of, or in combination with, the bonding agent.
1. A DR detector comprising:
a frame;
a cover secured to the frame; and
a frame groove formed in the frame, the groove having a bonding agent or adhesive therein for securing the cover to the frame,
wherein the cover comprises a cover groove facing the frame groove, the cover groove parallel to and overlapping the frame groove, the cover groove having a bonding agent or adhesive therein for securing the cover to the frame,
wherein the bonding agent or adhesive contacts both the frame and the cover,
wherein the frame is made from aluminum and the cover is made from carbon fiber,
wherein the frame groove includes a raised central portion that extends from a center of the frame groove into the cover groove, and
wherein the raised central portion of the frame groove is spaced from an interior groove surface of the cover groove by a gap, and wherein the gap is filled with a bonding agent or adhesive.
2. The DR detector of claim 1 , wherein the cover groove, the frame groove and the raised central portion are linear and are parallel to an outermost edge of the DR detector.
3. A digital radiographic (DR) detector comprising:
a multilayer structure including a two dimensional array of photosensors configured to capture radiographic images;
a rectangular frame having a top side, a bottom side, an inside surface and an outside surface;
a top cover secured to the top side of the frame;
a bottom cover secured to the bottom side of the frame, wherein the top cover, the bottom cover and the frame form an enclosure surrounding all sides of the multilayer structure, the inside surface of the frame faces the multilayer structure, and wherein the outside surface of the frame comprises an exterior edge of the detector;
a frame groove formed in the top side of the frame, the frame groove extending along the top side of the frame between the inside surface and the outside surface of the frame, the frame groove having a bonding agent therein for securing the top cover to the top side of the frame; and
a cover groove formed in the bottom side of the top cover, the cover groove extending around the bottom side of the top cover adjacent to an outer edge of the top cover, the cover groove facing the frame groove, the cover groove receiving the bonding agent therein for securing the top cover to the top side of the frame.
4. The DR detector of claim 3 , wherein the cover groove is narrower than the frame groove.
5. The DR detector of claim 4 , further comprising a conductive layer on the bottom side of the top cover, wherein a portion of the conductive layer that is adjacent to the cover groove faces a bottom of the frame groove.
6. The DR detector of claim 5 , further comprising a raised rib extending from the bottom of the frame groove beyond the top surface of the frame and into the cover groove.
7. The DR detector of claim 3 , further comprising a raised rib extending from the bottom of the frame groove beyond the top surface of the frame and into the cover groove.
8. The DR detector of claim 7 , wherein the raised rib is formed along the entire length of the frame groove.
9. The DR detector of claim 8 , wherein the raised rib is spaced from a groove surface of the cover groove by a gap, and wherein the gap comprises the bonding agent.
10. The DR detector of claim 7 , wherein the cover groove, the frame groove and the raised rib are parallel to the outside surface of the frame.
11. A digital radiographic (DR) detector comprising:
a multilayer structure including a two dimensional array of photosensors configured to capture radiographic images;
a rectangular frame having a top side, a bottom side, an inside surface and an outside surface;
a top cover secured to the top side of the frame;
a bottom cover secured to the bottom side of the frame, wherein the top cover, the bottom cover and the frame form an enclosure surrounding all sides of the multilayer structure, the interior surface of the frame faces the multilayer structure, and wherein the outside surface of the frame comprises an exterior edge of the detector;
a frame groove formed in the top side of the frame, the frame groove extending along the top side of the frame between the inside surface and the outside surface of the frame, the frame groove having a bonding agent therein for securing the top cover to the top side of the frame; and
a plurality of circular recesses formed on the bottom side of the top cove, the circular recesses facing the frame groove and overlapping the frame groove, the circular recesses having the bonding agent therein in contact with the top cover for securing the top cover to the frame.
12. The DR detector of claim 11 , wherein centers of each of the circular recesses are offset from a center of the frame groove.
13. The DR detector of claim 12 , further comprising a conductive layer on the bottom side of the top cover, wherein a portion of the conductive layer that is adjacent to the circular recess faces a bottom of the frame groove.
14. The DR detector of claim 11 , wherein the frame groove is parallel to the outside surface of the frame.
