Abstract
A system includes a catheter, a display system, and a control system in communication with the catheter and the display system. The control system includes one or more processors configured for receiving a set of model points of a model of one or more passageways of a patient and receiving a first set of measured points collected from within the patient passageways. Each point includes coordinates within a surgical environment occupied by the patient. The one or more processors are also configured for generating a first registration between the set of measured points and the set of model points, generating a second registration between a second set of measured points and the set of model points, and determining, after generating the first and second registrations, whether to implement the second registration in place of the first registration.
