  • Interactive segmentation
    Patent number: 10147185
    Abstract: A method for three-dimensional interactive segmentation, including: receiving a three-dimensional medical image of an interior volume of a patient's body; automatically performing three dimensional segmentation on the three dimensional medical image to detect and define a region of interest, wherein the performing of the three dimensional segmentation comprises automatically determining a boundary defining the region of interest; receiving from a user spatial information indicating one or more regions of disagreement in the three-dimensional medical image with respect to the determined boundary; and updating the three dimensional segmentation of the three dimensional medical image based on the spatial information received from the user, wherein the updating comprises updating the determined boundary based on the spatial information to redefine the area of interest.
    Type: Grant
    Filed: September 8, 2015
    Date of Patent: December 4, 2018
    Assignees: B.G. NEGEV TECHNOLOGIES AND APPLICATIONS LTD., AT BEN-GURION UNIVERSITY, MOR RESEARCH APPLICATIONS LTD.
