Abstract

A method and system for determining the position of a C-arm of an X-ray system is disclosed. The method includes obtaining a primary X-ray image of a desired location on a patient's body, obtaining a secondary X-ray image of the desired location on the patient's body, adjusting the secondary X-ray image with respect to the primary X-ray image using one or more touch based gestures, determining the subsequent location for X-ray imaging on the patient's body, and positioning the C-arm of the X-ray system to the subsequent location for X-ray imaging on the patient's body.

First claim

The invention claimed is:

1. A method for determining a position of a C-arm of an X-ray system, the method comprising:
obtaining a primary X-ray image of a desired location on a patient's body;
obtaining a secondary X-ray image of the desired location on the patient's body;
overlaying the secondary X-ray image over the primary X-ray image;
displaying the primary X-ray image and the overlaid secondary X-ray image on a touch-sensitive display;
adjusting a position of the secondary X-ray image with respect to the primary X-ray image based on at least one touch-based gesture on the touch-sensitive display to provide an adjusted secondary X-ray image;
determining a subsequent location for X-ray imaging on the patient's body using the adjusted secondary X-ray image; and
positioning the C-arm of the X-ray system to the subsequent location for X-ray imaging on the patient's body.

2. The method of claim 1 , wherein the determining comprises:
computing a deviation of a center of the primary X-ray image from a center of the adjusted secondary X-ray image; and
determining a distance that the C-arm of the X-ray system is to be moved along one or more of an X, Y, or Z axis using the computed deviation.

3. The method of claim 1 , further comprising:
automatically positioning the C-arm of the X-ray system based on the determined subsequent location on the patient's body.

4. The method of claim 1 , wherein the secondary X-ray image is a copy of the primary X-ray image.

5. The method of claim 1 , further comprising:
obtaining an X-ray image at the subsequent location on the patient's body.

6. The method of claim 1 , wherein the at least one touch-based gesture comprises a finger or a stylus based action of swiping, tapping, scrolling, panning, rotating, and pinch to zoom on the touch-sensitive display.

7. A system for determining a position of a C-arm of an X-ray system, the system comprising:
a touch-sensitive display;
a processing unit;
an image database coupled to the processing unit;
a memory coupled to the processing unit, the memory comprising a positioning module configured to:
obtain a primary X-ray image of a desired location on a patient's body;
obtain a secondary X-ray image of the desired location on the patient's body;
overlay the secondary X-ray image over the primary X-ray image;
displaying the primary X-ray image and the overlaid secondary X-ray image on the touch-sensitive display;
adjust the secondary X-ray image with respect to the primary X-ray image based on at least one touch-based gesture on the touch-sensitive display to provide an adjusted secondary X-ray image;
determine a subsequent location for X-ray imaging on the patient's body using the adjusted secondary X-ray image; and
position the C-arm of the X-ray system to the subsequent location for X-ray imaging on the patient's body.

8. The system of claim 7 , wherein the positioning module is further configured to:
compute a deviation of a center of the primary X-ray image from a center of the adjusted secondary X-ray image; and
determine a distance that the C-arm of the X-ray system is to be moved in X, Y and Z axes.

9. The system of claim 7 , wherein the positioning module is further configured to automatically position the C-arm of the X-ray system based on the determined subsequent location on the patient's body.

10. The method of claim 2 , further comprising:
automatically positioning the C-arm of the X-ray system based on the determined subsequent location on the patient's body.

11. The method of claim 10 , wherein the secondary X-ray image is a copy of the primary X-ray image.

12. The method of claim 11 , further comprising:
obtaining an X-ray image at the subsequent location on the patient's body.

13. The method of claim 12 , wherein the at least one touch-based gesture comprises a finger or a stylus based action of swiping, tapping, scrolling, panning, rotating, and pinch to zoom on the touch-sensitive display.

14. The method of claim 2 , wherein the secondary X-ray image is a copy of the primary X-ray image.

15. The method of claim 14 , further comprising:
obtaining an X-ray image at the subsequent location on the patient's body.

16. The method of claim 15 , wherein the at least one touch-based gesture comprises a finger or a stylus based action of swiping, tapping, scrolling, panning, rotating, and pinch to zoom on the touch-sensitive display.

17. The method of claim 2 , further comprising:
obtaining an X-ray image at the subsequent location on the patient's body.

18. The method of claim 17 , wherein the at least one touch-based gesture comprises a finger or a stylus based action of swiping, tapping, scrolling, panning, rotating, and pinch to zoom on the touch-sensitive display.

19. The method of claim 2 , wherein the at least one touch-based gesture comprises a finger or a stylus based action of swiping, tapping, scrolling, panning, rotating, and pinch to zoom on the touch-sensitive display.
