SYSTEMS AND METHODS FOR IMAGING A BODY REGION USING IMPLANTED MARKERS

Abstract: apparatus, systems, and methods are provided for localization of a region within a patient's body using markers implanted within the region. in an exemplary embodiment, a probe includes a distal end for placement against a surface of the region; one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region; a light source for delivering light pulses into the region whereupon the markers modulate reflected signals. a processor of the probe processes the modulated reflected signals at one or more of the surface locations to determine marker locations within the region to obtain a reference frame, determine distance values corresponding to distances from the respective markers to the distal end at each of the surface locations, and determine coordinates of the surface locations relative to the reference frame to generate a three dimensional model of the body region.
