4. The system of claim 1, wherein the system operational data comprises current X-ray source settings.

5. The system of claim 4, wherein the handheld interface device is configured to receive a user input to change a current X-ray source setting, and to communicate the change to the imaging system.

6. The system of claim 1, wherein the handheld interface device is configured to permit user initiation of an X-ray exposure, and wherein the imaging system provides a feedback signal to the handheld interface device confirming the exposure is being executed.

7. The system of claim 6, wherein the handheld interface device is configured to vibrate in response to the feedback signal.

8. The system of claim 6, wherein the handheld interface device is configured to illuminate an LED in response to the feedback signal.

9. The system of claim 6, wherein the handheld interface device is configured to emit an audible tone or tone sequence in response to the feedback signal.

10. The system of claim 1, wherein the imaging system is configured to inhibit operation of the X-ray source, and wherein the system operational data comprises an indication that the X-ray source operation is inhibited.

11. The system of claim 1, wherein the imaging system is configured to receive a user input requesting an audible locator signal from the handheld interface device and to transmit a signal based upon the user input to the handheld interface device that causes the handheld interface device to output the audible locator signal.

12. The system of claim 1, wherein at least one of the imaging system and the handheld interface device is configured to determine a strength of a wireless signal therebetween, and at least one of the imaging system and the handheld device is configured to emit a user-perceptible signal indicating that the system and the device are greater than a desired distance apart.

13. The system of claim 1, wherein the handheld interface device comprises a battery, and wherein the battery in the handheld interface device is recharged through direct contact with charge contacts in a holder or charge cradle.

14. The system of claim 1, wherein the handheld interface device comprises a battery, and wherein the battery in the handheld interface device is recharged through contactless power transfer while the handheld interface device is located in a holder or charge cradle.

15. The system of claim 1, wherein the handheld interface device comprises a battery, and wherein the battery in the handheld interface device is recharged by photovoltaic cells located in the handheld interface device.

16. The system of claim 1, wherein the handheld interface device comprises a battery, and wherein the battery in the handheld interface device is recharged by a microelectricalmechanical system located in the handheld interface device.

17. The system of claim 1, wherein the handheld interface device comprises a battery, and wherein the battery in the handheld interface device is recharged by a radiofrequency energy harvester device located in the handheld interface device.

18. An X-ray system comprising:

a handheld X-ray interface device comprising a wireless interface for communicating with an imaging system and for receiving system operational data from the imaging system, wherein the handheld X-ray interface device is configured to provide a user detectable indication of the imaging system operational status based upon the received data, the system operational data comprising a charge status of at least one battery of the imaging system for powering an X-ray source and movement of the imaging system from a location to another location for imaging via a wheeled mobile system, and wherein the handheld X-ray interface device is configured to receive and to transmit to the imaging system a user command to move the wheeled mobile system.
