Abstract:
Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.

Claim (Index 10):
The system of  claim 7 :\n wherein determining locations of the reference fiducial markers relative to the defined coordinate system comprises:\n identifying the reference spherical markers, \n regression fitting each of the identified reference spherical markers with an ideal sphere shape, and \n determining locations of the reference spherical markers using the regression-fitted reference spherical markers; and \n wherein determining locations of the mobile fiducial markers in the co-registered intra-operative image data and three-dimensional representation of the portion of the bone comprises:\n identifying the mobile spherical markers, \n regression fitting each of the identified mobile spherical markers with an ideal sphere shape, and \n determining locations of the mobile spherical markers using the regression-fitted reference spherical markers.
