Systems, methods and devices for correlating reference locations using image data
First Claim
1. A circuit-implemented method for use with an actual probe within an anatomical structure, the method comprising:
- for a virtual probe at a virtual location within a model of the anatomical structure, generating virtual image data captured by the virtual probe;
assessing the virtual image data through a probabilistic comparison of the virtual image data to actual image data captured by the actual probe at an actual location;
based upon the assessment, updating a correlation between the actual location of the actual probe and a sensed location of the actual probe to provide synchronicity between the sensed location and actual location; and
for maintaining the synchronicity between a subsequently sensed location and subsequent actual location, using the assessment to select a new virtual location for the virtual probe.

Abstract
A variety of embodiments relate to systems, methods, circuits and devices are implemented to perform location-based correlations. One such embodiment relates to a circuit-implemented method for use with an actual probe within an anatomical structure. For a virtual probe at a virtual location within a model of the anatomical structure, virtual image data captured by the virtual probe is generated. The virtual image data is assessed through a probabilistic comparison of the virtual image data to actual image data captured by the actual probe at an actual location. Based upon the assessment, a correlation is updated between the actual location of the actual probe and a sensed location of the actual probe to provide synchronicity between the sensed location and actual location. For maintaining the synchronicity between a subsequently sensed location and subsequent actual location, the assessment is used to select a new virtual location for the virtual probe.
