Abstract

Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms. This portability feature can be particularly useful in multi-suite medical and dental offices where a single x-ray device can be used as a digital x-ray camera in multiple offices instead of requiring a separate device in every office.

Claims

1. A portable x-ray device, comprising:

a housing containing an x-ray source and an integrated power system containing an internal power source;

integrated display means comprising an LCD screen; and

detecting means structurally unattached to the housing.

2. The device of claim 1, wherein the detecting means is electrically coupled to the x-ray device.

3. The device of claim 1, wherein the detecting means electrically communicates with the x-ray device using wireless technology.

4. The device of claim 1, wherein the device is a hand-held device.

5. The device of claim 1, wherein the device has a high current load for radiographic imaging.

6. The device of claim 1, wherein the power source can be removed from the housing.

7. The device of claim 1, wherein the power system comprises a plurality of power supplies with each power supply providing a power ranging from about 20 kV to about 50 kV.

8. The device of claim 1, wherein the x-ray source is shielded with a low-density insulating material containing a high-Z substance.

25. The device of claim 1, further comprising a controllable display means.

26. The device of claim 25, wherein the controllable display means is integrated into the housing.

27. The device of claim 25, wherein the controllable display means is external to the x-ray device.

28. The device of claim 25, wherein the controllable display means comprises a portable electronic device.

9. A hand-held x-ray device, comprising:

a housing containing an x-ray source, an integrated power system containing an internal power source, and integrated display means comprising an LCD screen; and

detecting means structurally unattached to the housing.

10. The device of claim 9, wherein the power source can be removed from the housing.

11. The device of claim 9, wherein the power system comprises a plurality of power supplies with each power supply providing a power ranging from about 20 kV to about 50 kV.

12. The device of claim 9, wherein the x-ray source is shielded with a low-density insulating material containing a high-Z substance.

29. The device of claim 9, wherein the device has a high current load for radiographic imaging.

13. A digital x-ray camera, comprising:

a housing containing an x-ray source, an integrated power system containing an internal power source, and integrated display means comprising an LCD screen; and

detecting means structurally unattached to the housing.

14. The camera of claim 13, wherein the power system comprises a plurality of power supplies with each power supply providing a power ranging from about 20 kV to about 50 kV.

15. The camera of claim 13, wherein the x-ray source is shielded with a low-density insulating material containing a high-Z substance.

16. A system for x-ray analysis, the system containing a digital x-ray camera with a housing containing an x-ray source, an integrated power system with an internal power source, and an integrated display means comprising an LCD screen, and detecting means structurally unattached to the housing.
