Abstract

A kit for converting an existing mobile or portable film X-ray examination apparatus typically configured solely for analog radiography to enable said examination apparatus for digital radiographic applications. The kit includes a tablet PC that is attached to the wheeled chassis of the mobile or portable apparatus, and an input/output device used to divert the exposure control signal from the user actuable exposure control switch of the apparatus to the tablet PC. The tablet PC includes image processing software that controls the operation of a digital flat panel detector. The tablet PC can further be used to separately control other mobile or portable apparatus or a facility or examination room that was previously configured only for analog radiography.

Claims

1. A X-ray diagnostic apparatus originally solely configured for analog-based radiography, said diagnostic apparatus including an X-ray generator assembly, an exposure control mechanism for use with X-ray film, and a conversion kit for converting the apparatus from analog to digital operation, said conversion kit including:

a tablet at said x-ray diagnostic apparatus, and is releasably attached to said apparatus, said tablet providing a user interface configured to allow user control of the X-ray diagnostic apparatus and having software enabling digital radiographic exposure control; and

circuitry configured for electrically routing an exposure control signal from said exposure control mechanism of said apparatus to said tablet, wherein said tablet is configured to control an exposure of at least one digital flat panel detector in lieu of a film X-ray cassette.

2. The apparatus as recited in claim 1, wherein said tablet includes a resident battery, said resident battery enabling powered operation thereof without otherwise influencing a power supply of said X-ray diagnostic apparatus.

3. The apparatus as recited in claim 1, further comprising a slot sized for housing said tablet when the tablet is attached to said X-ray diagnostic apparatus.

4. The apparatus as recited in claim 1, wherein said circuitry includes an I/O device that routs the exposure control signal from a hand control of said exposure control mechanism to said tablet.

5. The apparatus as recited in claim 1, including means for linking said at least one digital flat panel detector with said tablet, said linking means drawing power from said tablet.

6. The apparatus as recited in claim 1, further comprising a switching mechanism for enabling selective operation between an analog mode and a digital mode of operation.

7. The apparatus as recited in claim 6, wherein said circuitry comprises an I/O device, and said switching mechanism comprises a jumper circuit provided in said I/O device.

8. The apparatus as recited in claim 1, wherein said apparatus includes a wheeled cart having a cover and an operator'"'"'s console with controls for operating said X-ray generator assembly, said conversion kit including a replacement cover configured for retaining said tablet at said apparatus.

9. A kit for converting a X-ray diagnostic apparatus originally solely configured for analog-based radiography into a digital radiography apparatus, said X-ray diagnostic apparatus including resident circuitry for controlling analog X-ray exposure triggered by a user-actuable exposure control, said conversion kit comprising:

a tablet having a user interface and software configured for providing digital radiographic exposure control in an imaging procedure that involves a digital flat panel detector;

a securing mechanism for releasably mounting said tablet at said apparatus; and

circuitry configured for diverting an exposure control signal from said user-actuated exposure control to said tablet.

10. The conversion kit as recited in claim 9, wherein said tablet is wirelessly connected to said digital flat panel detector.

11. The conversion kit as recited in claim 9, wherein said tablet is powered by at least one resident battery.

12. The conversion kit as recited in claim 11, wherein said tablet does not draw power from said diagnostic apparatus.

13. The conversion kit as recited in claim 9, wherein said tablet is connected by a wired connection to said digital flat panel detector.

14. The conversion kit as recited in claim 9, further including a replacement cover for said apparatus, said replacement cover including at least one recess for retaining said tablet at said apparatus.

15. The conversion kit as recited in claim 9, wherein said tablet includes a virtual keyboard.

16. The conversion kit as recited in claim 9, wherein said circuitry includes an I/O device having ports for receiving the exposure control signal and for directing said signal to a X-ray generator and to said tablet.

17. A method performed by a converted X-ray apparatus obtained by converting a X-ray apparatus originally configured solely for analog-based radiography, said apparatus including an X-ray generator, a resident power supply, and a control for controlling the exposure of X-rays, said method including:

diverting an exposure control signal from said control to a tablet, said tablet including resident software for controlling the X-ray generator and a digital flat panel detector, wherein the tablet is a part of a conversion kit for converting the X-ray apparatus from analog operation to digital operation, and wherein the tablet is mounted at the x-ray apparatus; and

controlling an exposure of said digital flat panel detector using said tablet.

18. The method as recited in claim 17, further comprising powering said tablet using a self contained battery and not drawing power from the resident power supply of said apparatus.

19. The method as recited in claim 17, wherein said tablet communicates wirelessly with said flat panel detector.

20. The method as recited in claim 17, wherein said tablet communicates using a wired connection with said flat panel detector.

21. The method as recited in claim 17, further comprising operating said tablet without drawing from the power supply of said diagnostic apparatus.

22. The method as recited in claim 17, wherein said apparatus comprises an I/O device, said I/O device having ports for interconnecting with exposure control leads of said apparatus.
