1. A method for identifying a position of a body structure that is to be registered, wherein a reference structure is attached to the body structure, said reference structure including at least one imaging structure and a plurality of artificial markers arranged at predetermined locations on said reference structure, the artificial markers having a known non-zero spatial offset from the at least one imaging structure, comprising:
imaging the body structure to obtain a data set describing a relationship between the body structure and the imaging structure; creating in the data set, with a computer hardware, artificial marker data corresponding to the locations of the artificial markers on said reference structure, said creating comprising using locations of the imaging structure in the data set and the known non-zero offset from the at least one imaging structure to create the artificial marker data in the data set; identifying, using the computer hardware, a position of the artificial markers to a navigation system; using the position of the artificial markers and the known relationship between the artificial markers and the imaging structure to identify, using the computer hardware, a position of the body structure in space. |
