A method and system for registering a bone of a patient with a computer assisted orthopaedic surgery system includes retrieving an image of the bone having indicia of the position of a magnetic source coupled thereto, determining first data indicative of the position of the magnetic source in a bone coordinate system, determining second data indicative of a correlation between a coordinate system of the image and the bone coordinate system based on the first data; and displaying an image of the bone based on the second data.

The invention claimed is: 1. A method for registering a bone of a patient with a computer assisted orthopaedic surgery system, the method comprising:retrieving an image of the bone including indicia of the position of a magnet implanted in the bone, the image defining an image coordinate system;determining a position of a reference array coupled to the bone, the reference array defining a bone coordinate system;determining first data indicative of the position of the magnet in the bone coordinate system by determining a location of the centroid of the magnet using the following equation:PB=RT[2]−1*(RT[1]* PM)wherein PB the location of the centroid of the magnet in the bone coordinate system, RT[1] is a first transformation matrix, RT[2] is a second transformation matrix, and PM is the location of the centroid of the magnet in the magnetic sensor array coordinate system;determining second data indicative of a correlation between the image coordinate system and the bone coordinate system based on the first data; anddisplaying an image of the bone in a position determined based on the second data.
