Publication number: 20230012778Abstract: Methods and apparatuses provide improved navigation through tubular networks such as lung airways by providing improved estimation of location and orientation information of a medical instrument (e.g., an endoscope) within the tubular network. Various input data such as image data, EM data, and robot data are used by different algorithms to estimate the state of the medical instrument, and the state information is used to locate a specific site within a tubular network and/or to determine navigation information for what positions/orientations the medical instrument should travel through to arrive at the specific site. Probability distributions together with confidence values are generated corresponding to different algorithms are used to determine the medical instrument's estimated state.Type: ApplicationFiled: July 27, 2022Publication date: January 19, 2023Applicant: Auris Health, Inc.Inventors: David S. Mintz, Atiyeh Ghoreyshi, Prasanth Jeevan, Yiliang Xu, Gehua Yang, Matthew Joseph Leotta, Charles V. Stewart

Patent number: 7177486Abstract: An iterative method and associated algorithm for performing image registration to map features in a first image to corresponding features in a second image in accordance with a transformation model. Upon convergence of a parameter vector associated with the model, a current bootstrap region includes and exceeds an initial bootstrap region that is initially established. During the iterations, the parameter vector is estimated by minimizing an objective function with respect to the parameter vector. Each iteration generates a next bootstrap region that minimally includes the current bootstrap region and may exceed the current bootstrap region. The model may change in successive iterations.Type: GrantFiled: April 7, 2003Date of Patent: February 13, 2007Assignee: Rensselaer Polytechnic InstituteInventors: Charles V. Stewart, Chia-Ling Tsai, Badri Roysam
