Abstract
Official abstract text for this publication.
A method for using an assembled three-dimensional image to construct a three-dimensional model for determining a path through a lumen network to a target. The three-dimensional model is automatically registered to an actual location of a probe by tracking and recording the positions of the probe and continually adjusting the registration between the model and a display of the probe position. The registration algorithm becomes dynamic (elastic) as the probe approaches smaller lumens in the periphery of the network where movement has a bigger impact on the registration between the model and the probe display.
First claim
Opening claim text (preview).
We claim: 1. A method of registering a computer model of a lumen network to an actual lumen network of a patient while navigating the lumen network with a probe, comprising: collecting data pertaining to an actual location of a probe by utilizing electromagnetic sensors located on the probe; processing successive data points of the probe location to establish a probe path through an actual lumen network of a patient; iteratively registering the probe path to a path shape in a…
