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 1):
A system comprising:\n at least one processor; and at least one computer-readable medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising:\n accessing first image data of at least a portion of a bone to which a reference fiducial marker array is fixed in advance of a surgical procedure, the reference fiducial marker array comprising at least three reference fiducial markers and the first image data being captured using a first imaging modality that is configured to image the reference fiducial markers and three-dimensional anatomic landmark data for the portion of the bone; \n generating a three-dimensional representation of the portion of the bone and the reference fiducial markers based on the first image data; \n defining a coordinate system for the three-dimensional representation of the portion of the bone; \n determining locations of the reference fiducial markers relative to the defined coordinate system; \n accessing intra-operative image data that includes the portion of the bone to which to the reference fiducial marker array is fixed and a mobile fiducial marker array that is attached to an instrument used in the surgical procedure on the portion of the bone, the mobile fiducial marker array comprising at least three mobile fiducial markers and the intra-operative image data being captured using a second imaging modality that is different than the first imaging modality and that is configured to image the reference fiducial markers and the mobile fiducial markers; \n co-registering the intra-operative image data with the three-dimensional representation of the portion of the bone by matching the reference fiducial markers included in the intra-operative image data to the determined locations of the reference fiducial markers relative to the defined coordinate system; \n 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; \n determining a three-dimensional spatial position and orientation of the instrument relative to the portion of the bone based on the determined locations of the mobile fiducial markers; \n comparing the three-dimensional spatial position and orientation of the instrument relative to the portion of the bone with a designed alignment of the instrument to the portion of the bone; \n based on comparison results, determining an indication of precision of alignment of the instrument in the surgical procedure on the portion of the bone relative to the designed alignment of the instrument to the portion of the bone; and \n providing output based on the determined indication of precision of alignment of the instrument in the surgical procedure relative to the designed alignment of the instrument.
