Abstract
A method for determining a location of an object relative to a body structure includes: providing a location of a first part of the object relative to a second part of the object, said second part different from said first part; attaching a marker device to the body structure; detecting a location of the marker device relative to the body structure; positioning the object relative to the body structure; detecting a location of the first part of the object relative to the marker device; and calculating a relative location of the second part of the object relative to the location of the body structure based on the location of the first part relative to the second part, the location of the marker device relative to the body structure, and the location of the first part relative to the marker array.
