Abstract

In some embodiments, a synthetic (virtual) orthopedic treatment device (e.g. a virtual external fixator representing a physical fixator attachable to a patient's anatomic structure) is displayed concurrently in two views (e.g. anterior-posterior and lateral) along corresponding digital medical images (e.g. X-rays), and rotation/translation user input received along one of the images is used to concurrently control both displays of the orthopedic treatment device to reflect the rotation/translation user input.

First claim

What is claimed is:

1. A computer system comprising at least one microprocessor configured to execute instructions to:
generate a first display of an orthopedic treatment device superimposed on a display of a first digital medical image, the display of the first digital medical image displaying a first view of a patient's anatomical structure, the first display of the orthopedic treatment device being a first graphical representation of a synthetic orthopedic treatment device representing a physical orthopedic treatment device;
concurrently with generating the first display of the orthopedic treatment device superimposed on the display of the first digital medical image, generate a second display of the orthopedic treatment device superimposed on a display of a second digital image, the display of the second digital medical image displaying a second view of the patient's anatomical structure from a different angle than the first view, the second display of the orthopedic treatment device being a second graphical representation of the synthetic orthopedic treatment device;
receive user input entered graphically on the first display of the orthopedic treatment device superimposed on the display of the first digital medical image, the user input controlling a motion of the synthetic orthopedic treatment device; and
in response to receiving the user input, update the first display of the orthopedic treatment device superimposed on the display of a first digital medical image and the second display of the orthopedic treatment device superimposed on the display of a second digital image to reflect the motion of the synthetic orthopedic treatment device.

2. The computer system of claim 1 , wherein the first view is an anterior-posterior (AP) view, and the second view is a lateral view.

3. The computer system of claim 1 , wherein the first view is a lateral view, and the second view is an anterior-posterior (AP) view.

4. The computer system of claim 1 , wherein the motion comprises a rotation motion.

5. The computer system of claim 1 , wherein the motion comprises a translation motion.

6. The computer system of claim 1 , wherein the motion comprises a rotation motion and a translation motion.

7. The computer system of claim 1 , wherein the orthopedic treatment device is an external fixator comprising a pair of rings interconnected by struts.

8. The computer system of claim 1 , wherein the at least one microprocessor is configured to execute instructions to per-form a relative scaling of the first digital medical image and the second digital medical image.

9. A non-transitory computer-readable medium encoding instructions which, when executed by a microprocessor of a computer system, cause the computer system to:
generate a first display of an orthopedic treatment device superimposed on a display of a first digital medical image, the display of the first digital medical image displaying a first view of a patient's anatomical structure, the first display of the orthopedic treatment device being a first graphical representation of a synthetic orthopedic treatment device representing a physical orthopedic treatment device;
concurrently with generating the first display of the orthopedic treatment device superimposed on the display of the first digital medical image, generate a second display of the orthopedic treatment device superimposed on a display of a second digital image, the display of the second digital medical image displaying a second view of the patient's anatomical structure from a different angle than the first view, the second display of the orthopedic treatment device being a second graphical representation of the synthetic orthopedic treatment device;
receive user input entered graphically on the first display of the orthopedic treatment device superimposed on the display of the first digital medical image, the user input controlling a motion of the synthetic orthopedic treatment device; and
in response to receiving the user input, update the first display of the orthopedic treatment device superimposed on the display of a first digital medical image and the second display of the orthopedic treatment device superimposed on the display of a second digital image to reflect the motion of the synthetic orthopedic treatment device.

10. The non-transitory computer readable medium of claim 9 , wherein the first view is an anterior-posterior (AP) view, and the second view is a lateral view.

11. The non-transitory computer readable medium of claim 9 , wherein the first view is a lateral view, and the second view is an anterior-posterior (AP) view.

12. The non-transitory computer readable medium of claim 9 , wherein the motion comprises a rotation motion.

13. The non-transitory computer readable medium of claim 9 , wherein the motion comprises a translation motion.

14. The non-transitory computer readable medium of claim 9 , wherein the motion comprises a rotation motion and a translation motion.

15. The non-transitory computer readable medium of claim 9 , wherein the orthopedic treatment device is an external fixator comprising a pair of rings interconnected by struts.

16. The non-transitory computer readable medium of claim 9 , wherein the at least one microprocessor is configured to execute instructions to perform a relative scaling of the first digital medical image and the second digital medical image.
