Abstract

A method of providing augmented reality using EM tracking techniques is disclosed herewith. An EM tracking sensor is provided on the head of surgeon. The position and orientation information obtained from the EM tracking technology is used to determine the transformation needed to superimpose preoperative data over live video feed in augmented reality.

A METHOD AND SYSTEM FOR PROVIDING AUGMENTED REALITY USING EM TRACKING

FIELD OF INVENTION

[0001]               The invention generally relates to providing augmented reality, more specifically to method of providing augmented reality using EM tracking. 

BACK GROUND OF THE INVENTION

[0002]               Augmented reality in a surgical setting involves augmenting reality (live video) with preoperative imaging (CT, MR, etc) in real time. The surgeon would wear a head mounted display and optical tracking technology is used to determine the transformation needed to superimpose the preoperative data over the live video feed.

[0003]               Optical markers are used in augmenting reality through optical tracking technology. However this involves an overhead of image processing and also imposes field of view restrictions, as the optical markers have to be visible all the time.

[0004]               Hence it will be beneficial to have a novel method for providing augmented reality through some other technology, for example, using EM tracking techniques.

SUMMARY OF INVENTION

[0005]               An embodiment of the invention describes a method of providing augmented reality through EM tracking.

[0006]               In augmented reality in a surgical setting involves augmenting reality (live video) with preoperative imaging (CT, MR, etc) in real time. The surgeon would wear a head mounted display and optical tracking technology is used to determine the transformation needed to superimpose the preoperative data over the live video feed. In an embodiment, the invention suggests to use the position and orientation information obtained from the EM tracking technology t...
