Abstract

A digital x-ray detector has a non-metallic housing. A two dimensional array of photosensors enclosed by the housing is in electrical communication with an electrical circuit formed on an interior surface of the housing.

First claim

What is claimed:

1. A digital x-ray detector comprising:
a non-metallic housing comprising two or more sections configured to be fastened together;
a two dimensional array of photosensors enclosed by the sections of the housing fastened together, the two dimensional array of photosensors configured to capture image signals from received radiation;
control electronics for acquiring image data from the captured image signals, the control electronics enclosed by the sections of the housing fastened together; and
a first electrical circuit inscribed on an interior surface of at least one of the sections of the housing,
wherein the interior surface faces toward the two dimensional array of photosensors, the first electrical circuit is in electrical communication with the control electronics, and wherein the first electrical circuit is in electrical communication with the photosensors to provide data communication between the control electronics and the photosensors.

2. The digital x-ray detector of claim 1 , wherein the first electrical circuit comprises an antenna.

3. The digital x-ray detector of claim 1 , further comprising one or more electronic chips mounted on the interior surface in electrical communication with the first electrical circuit.

4. The digital x-ray detector of claim 1 , further comprising a second electrical circuit formed on an interior surface of the housing and having a planar shape to form an electrical shield.

5. The digital x-ray detector of claim 1 , further comprising a second electrical circuit formed on an interior surface of the housing and having a crosshatch pattern to form an electrical shield.

6. The digital x-ray detector of claim 1 , wherein the interior surface of the housing comprises two perpendicular surfaces and wherein the first electrical circuit comprises at least three parallel continuous conductive tracks traversing the two perpendicular surfaces.

7. The digital x-ray detector of claim 1 , further comprising a battery configured to provide electrical power for operating the detector.

8. The digital x-ray detector of claim 1 , wherein the housing is formed from a plastic material selected from the group consisting of polyvinyl chloride, polyethylene terephthalate, acrylonitrile-butadiene-styrene, polycarbonate, polyimide, liquid crystal polymer, polyetherimide, polyphenylene sulfide, polysulfone, polystyrene, glycol-modified polyester, polypropylene, or a combination thereof.

9. The digital x-ray detector of claim 1 , wherein the housing is formed from a composite material.

10. The digital x-ray detector of claim 1 , wherein the two dimensional array of photosensors is formed on an interior surface of the housing.

11. The digital detector of claim 2 , wherein a width of the antenna is about 0.2 inches or less, a length of the antenna is about 2 inches or less, and a thickness of the antenna ranges from about 3 μm to about 10 μm.

12. The digital detector of claim 6 , wherein the first electrical circuit comprises conductive tracks each having a width from about 75 μm up to about 150 μm and separated by gaps of about 75 μm up to about 200 μm.

13. The digital detector of claim 12 , wherein the conductive tracks comprise a thickness of about 3 μm up to about 10 μm.

14. The digital detector of claim 3 , wherein two of the mounted electronic chips are configured to communicate digital image data over the first electrical circuit.

15. A method for forming a digital radiography detector comprising an array of photosensors, the method comprising:
molding housing cover sections using a plastic or composite material;
conditioning a pattern on an internal surface of at least one of the housing cover sections for forming metallization tracks thereon;
plating the conditioned pattern to form the metallization tracks on the internal surface of said at least one of the housing cover sections; and
fastening the housing cover sections together including connecting at least one of the housing cover sections to the array of photosensors to complete an electrical connection from the photosensors to the metallization tracks to provide image data communication from the photosensors over the metallization tracks, and including enclosing the array of photosensors by the step of fastening the housing cover sections together.

16. The method of claim 15 , further comprising installing a battery within the housing cover sections and configuring the battery to provide power for operating the detector.

17. The method of claim 15 , further comprising populating the conditioned pattern with electronic components.

18. The method of claim 15 , wherein the metallization tracks form part of a shield against electromagnetic interference.

19. The method of claim 15 , wherein fastening the housing cover sections together completes a circuit, ground, or shield connection.

20. A digital radiographic detector comprising:
a housing enclosing a radiographic detector array, the detector array for capturing radiographic image data from received radiation;
a battery enclosed by the housing;
conductive tracks inscribed on an interior surface of the housing, the conductive tracks electrically connected to the detector array, the conductive tracks including an antenna; and
an integrated circuit chip enclosed by the housing and electrically connected to the conductive tracks, the integrated circuit chip configured to receive the radiographic image data from the detector array over the conductive tracks and to transmit the radiographic image data over the antenna,
wherein the battery is configured to provide electric power for operating the detector.
