Abstract

Systems and methods are disclosed involving an instrument, an instrument tracking device for tracking movement of the instrument, a first boundary tracking device for tracking movement of a first virtual boundary associated with an anatomy of a patient to be treated by the instrument, and a second boundary tracking device for tracking movement of a second virtual boundary associated with a periphery of an opening in the patient to be avoided by the instrument. One or more controllers receive information associated with the tracking devices including positions of the instrument relative to the first and second virtual boundaries, detect movement of the first and second virtual boundaries relative to one another, and generate a response upon detecting movement of the first and second virtual boundaries relative to one another.
