摘要： 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.

摘要： The present disclosure allows for more controlled modification of the input data to a Rapid Manufacturing Technologies (RMT) machinery to compensate for systematic error of the manufacturing process, such as directional build discrepancies, by performing the opposite effect to the input data. The modification is achieved with minimal unwanted distortions introduced to other portions of the structure to be built by decoupling the global scaling effects on the whole structure from the desired local effects on certain portions.

摘要： Instrument that is made to match the perimeter shape of a Patient Specific Knee Implant (PSKI) with features for locating holes in the distal femur such that the posts or lugs in the femoral implant locate the femoral implant centered medial-laterally within an acceptable degree of precision to prevent overhang of either the medial or lateral side of the femoral implant over the perimeter of the distal femur bone resections. Patient specific implant technology, in which a three-dimensional model of at least a portion of a bone is accessed and a three-dimensional solution volume is defined based on resection cuts used in fitting an implant on the portion of the bone. An outline representation of at least a portion of an outer surface of a periphery of the resultant bone volume is determined and the outline representation is used in one or more operations related to instrument matching.
