  • Measurement of thin-layered structures in X-ray computer tomography
    Patent number: 8644574
    Abstract: A method for reconstructing an image includes receiving tomographic data representative of an image signal; deriving, from the image signal, a plurality of components; identifying a spatial location associated with maximum phase congruency of the components; incorporating, into an image, an edge at the spatial location; and providing an output representative of the image.
    Type: Grant
    Filed: October 3, 2007
    Date of Patent: February 4, 2014
    Assignee: The Brigham and Women's Hospital, Inc.
    Inventors: Raúl San José Estépar, George R. Washko, Edwin K. Silverman, John J. Reilly, Ron Kikinis, Carl-Fredrik Westin

  • MRA segmentation using active contour models
    Patent number: 6718054
    Abstract: A method and system of providing segmentation of volumetric three-dimensional image data set such as MRA images. Initially, a three-dimensional MRA volume is input. An initial surface S is then generated by thresholding the input. A signed distance function v to S is then generated, where v=v(x,t) and S is the zero level set of v(·,0).
