Patent number: 8270694Abstract: 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.Type: GrantFiled: April 23, 2009Date of Patent: September 18, 2012Inventors: Aditya Koolwal, Christopher R. Carlson, Federico Barbagli
