Abstract:
1. A method for determining a location of an object relative to a body structure, comprising: a) providing a location of a first point or first plane corresponding to a first part of the object relative to a second point or second plane corresponding to a second part of the object, said second part different from said first part; b) attaching a body marker device to the body structure; c) detecting a location of the body marker device relative to the body structure; d) positioning the object relative to the body structure; e) detecting a location of the first point or first plane relative to the body marker device, said detecting performed without using a marker array attached to the object; and f) 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 point or first plane relative to the second point or second plane, the location of the body marker device relative to the body structure, and the location of the first point or first plane relative to the body marker device.
