Abstract

An image guided surgical system and method for correction of automated image registration via user interaction. The system and method comprising at least one imaging apparatus adapted to acquire a first image and a second image of a region of interest of a subject, a registration component adapted to perform a registration of the second image to a dataset of the first image, at least one display for displaying a visualization of the registration of the second image to a dataset of the first image as it is occurring, and a user interface for manipulating the visualization of the registration to correct any misalignments between the first image and the second image in the registration.

Claims

1. A medical navigation system comprising:

at least one imaging apparatus adapted to acquire a first image and a second image of a region of interest of a subject;

a registration component adapted to perform a registration of the second image to a dataset of the first image;

at least one display for displaying a visualization of the registration of the second image to a dataset of the first image as it is occurring; and

a user interface for manipulating the visualization of the registration to correct any misalignments between the first image and the second image in the registration.

2. The system of claim 1, wherein the first image is acquired by a first imaging apparatus.

3. The system of claim 1, wherein the first image is acquired prior to a medical procedure and transferred and stored on a storage device of the medical navigation system.

4. The system of claim 3, wherein the second image is acquired by a second imaging apparatus.

5. The system of claim 4, wherein the second image is acquired during the medical procedure.

6. The system of claim 1, wherein the registration component includes a feedback mechanism for user interaction with the registration process.

7. The system of claim 6, wherein the feedback mechanism provides visualization of the second image and the dataset of the first image on the display.

8. The system of claim 1, wherein the acquired first image data is selected from the group consisting of computed tomography data, magnetic resonance data, positron emission tomography data, ultrasound data, and X-ray data and any combinations thereof.

9. The system of claim 1, wherein the acquired second image data is selected from the group consisting of computed tomography data, magnetic resonance data, positron emission tomography data, ultrasound data, and X-ray data and any combinations thereof.

10. The system of claim 1, wherein the at least one display is a touch screen display with graphical inputs.

11. The system of claim 1, wherein the user interface includes standard input tools selected from a group consisting of a mouse, a keyboard, a joystick, a plurality of pushbuttons, and a touch screen display.

12. A method for performing image registration comprising:

acquiring a first image and a second image of a region of interest of a patient;

performing a registration of the second image to a dataset of the first image;

viewing a visualization of the registration on at least one display as the registration is occurring; and

manipulating the visualization of the registration to correct any misalignments between the first image and the second image in the registration using a user interface.

13. The method of claim 12, further comprising the step of terminating the registration and re-starting the registration with a new set of images.

14. The method of claim 12, wherein the first image is acquired prior to a medical procedure and transferred and stored on a storage device of the medical navigation system.

15. The method of claim 14, wherein the second image is acquired during the medical procedure.

16. The method of claim 12, wherein the registration includes a feedback mechanism for user interaction with the registration process.

17. The method of claim 16, wherein the feedback mechanism provides visualization of the second image and the dataset of the first image on the display.

18. The method of claim 12, wherein the at least one display is a touch screen display with graphical inputs.

19. The method of claim 12, wherein the user interface includes standard input tools selected from a group consisting of a mouse, a keyboard, a joystick, a plurality of pushbuttons, and a touch screen display.

20. A computer-readable medium including a set of instructions for execution on a computer, the set of instructions comprising:

an acquisition routine for acquiring a first image and a second image of a region of interest of a patient;

a registration routine for registering the second image to a dataset of the first image;

a visualization routine for visualizing the registration on a display while the registration is proceeding; and

a user interaction routine for manipulating the registration to correct any misalignments between the first image and the second image.
