POSITIONING METHOD AND APPARATUS FOR MOUNTING A TRACKER

摘要

A method for apposing one body to another across a soft tissue interface which minimizes relative movement between the two bodies by using normal constraints to attenuate skin motion artifacts. Apparatuses based on this method consist of a multiplicity of contact surfaces and means for applying seating forces; and may include adjustment mechanisms for accommodating a range of body sizes and if desired sensing means to permit compensating for small relative motions and monitoring correct performance of the system may be provided.
