Abstract
A registration fixture for use with a surgical navigation system for registration of a medical image or images to a three-dimensional tracking space that includes a first ring having at least one tracking marker, a second ring coupled to the first ring having at least one tracking marker and wherein the first ring and the second ring are spaced apart from one another and further include optical markers.
Claims1
A surgical navigation system with a registration fixture for registration of 2-dimensional medical images to a three-dimensional camera tracking space comprising:
- a registration fixture adapted to be attached to an x-ray imaging device and including:
- a first structure having a plurality of spaced radiopaque markers in a first pattern;
- a second structure having a plurality of spaced radiopaque markers in a second pattern, the first and second structures being spaced from each other;
- and
- a plurality of fixed optical markers;
- a surgical system including:
- tracking cameras for tracking the optical markers of the registration fixture;
- a processor configured to:
- receive first and second 2-dimensional medical images taken at different angles while the tracking cameras are tracking the optical markers of the registration fixture;
- and
- register the received first and second medical images with a 3-dimensional optical tracking space based on vectors extending between an emitter and a collector of the imaging device that form a conical pattern so as to map points on the first and second medical images to the 3-dimensional optical tracking space.
