Abstract

A system and method for controlling a medical imaging device is provided. The system includes a medical imaging device. The system further includes a medical instrument. Further, the system includes a navigation subsystem that is configured to track the medical instrument. Furthermore, the system includes a control subsystem that communicates with the navigation subsystem. The control subsystem is configured to correlate at least one of orientation, position and motion of the medical instrument with a function of the medical imaging device. The control subsystem is further configured to direct the medical imaging device to perform the function associated with the medical imaging device, based on the correlation.

Claims

1. A system for controlling a medical imaging device, comprising:

a medical imaging device;

a medical instrument having at least one tracking element, said medical instrument selectively engageable between a navigation function and a control function that is associated with operation of said medical imaging device;

a navigation subsystem comprising (i) a transmitter adapted to transmit a signal that is received by said tracking element; and

(ii) a navigation processing unit in communication with said transmitter and said at least one tracking element in order to track the orientation, position, and motion of said medical instrument; and

a control subsystem in communication with said navigation subsystem, said control subsystem having a control processing unit that is operable to correlate at least one of the orientation, position, and motion of said medical instrument with a function associated with operation of said medical imaging device when said medical instrument operates in the control function, said control subsystem also being operable to direct said medical imaging device to perform the function associated with operation of said medical imaging device based on at least one of the orientation, position, and motion of said medical instrument.

2. The system of claim 1, wherein the function associated with operation of said medical imaging device includes at least one of a movement function and an imaging function of said medical imaging device.

3. The system of claim 1, further comprising a display unit in communication with said medical imaging device and said navigation subsystem, wherein said navigation subsystem is adapted to display the navigation function of said medical instrument, wherein the navigation function includes at least one of the orientation, position, and motion of said medical instrument in relation to an image obtained by said medical imaging device.

4. The system of claim 3, wherein said medical instrument further comprises an engagement member that is in communication with at least one of said navigation and control processing units, said engagement member being configured to selectively engage said medical instrument between the navigation function and the control function associated with operation of said medical imaging device.

5. The system of claim 4, wherein said engagement member comprises at least one of a button, switch, and dial.

6. The system of claim 1, wherein said medical imaging device is a fluoroscopic C-arm comprising a source and a detector.

7. The system of claim 1, wherein said medical instrument is a handheld medical instrument comprising at least one of a probe, surgical drill, cutting tool, and scope.

8. The system of claim 1, wherein said navigation subsystem is one of an ultrasound, inertial position, optical and electromagnetic navigation subsystem.

9. The system of claim 1, wherein said medical instrument operates as a joystick to direct movement of the medical imaging device in the control function.

10. A method of controlling a medical imaging device, comprising:

tracking a medical instrument;

using a processing unit to correlate orientation, position and motion of the medical instrument with operation of the medical imaging device; and

controlling the medical imaging device based on said correlating,

wherein said controlling comprises operating the medical instrument as a joystick to direct movement of the medical imaging device.

11. The method of claim 10, wherein said tracking comprises tracking the medical instrument with one of an ultrasound, inertial position, optical and electromagnetic navigation subsystem.

12. The method of claim 10, wherein said controlling comprises at least one of moving the medical imaging device and imaging with the medical imaging device.

13. The method of claim 10, further comprising displaying at least one of the orientation, position, and motion of the medical instrument in relation to images obtained by said medical imaging device.

14. The method of claim 13, further comprising selecting between said controlling and said displaying.

15. A system for controlling a medical imaging device, comprising:

a medical imaging device;

a medical instrument;

a navigation subsystem configured to track said medical instrument; and

a control subsystem in communication with said navigation subsystem, said control subsystem being operable to control all movement and imaging functions of said medical imaging device through said medical instrument.

16. The system of claim 15, wherein said navigation subsystem is configured to track at least one of an orientation, position, and motion of said medical instrument;

and said control subsystem being operable to control said medical imaging device based on at least one of the orientation, position, and motion of said medical instrument.

17. The system of claim 15, wherein said control subsystem is operable to control at least one of a movement function and an imaging function of the medical imaging device.

18. The system of claim 15, further comprising a display unit in communication with said medical imaging device and said navigation subsystem, wherein said navigation subsystem is adapted to display at least one of an orientation, position, and motion of said medical instrument in relation to an image obtained by said medical imaging device.

19. The system of claim 18, wherein said medical instrument further comprises an engagement member that is in communication with at least one of said navigation and control subsystems, said engagement member being configured to selectively engage said medical instrument between navigation and medical imaging device control functions.

20. The system of claim 19, wherein said engagement member comprises at least one of a button, switch, and dial.

21. The system of claim 19, wherein the navigation function includes at least one of the orientation, position, and motion of said medical instrument in relation to an image obtained by said medical imaging device.

22. The system of claim 15, wherein said medical imaging device is a fluoroscopic C-arm comprising a source and a detector.

23. The system of claim 15, wherein said medical instrument is a handheld medical instrument comprising at least one of a probe, surgical drill, cutting tool, and scope.

24. The system of claim 15, wherein said navigation subsystem is one of an ultrasound, an inertial position, optical and electromagnetic navigation subsystem.

25. The system of claim 15, wherein said medical instrument operates as a joystick to direct movement of the medical imaging device.
