  • Efficient user interaction with polygonal meshes for medical image segmentation
    Patent number: 9014446
    Abstract: An apparatus for delineating a structure of interest includes: a plane selection interface for selecting a contouring plane of selectable orientation in a three-dimensional image or map; a contouring interface for defining a contour in the selected contour plane; and a mesh constructor configured to construct a three-dimensional polygonal mesh delineating the structure of interest in the three-dimensional image or map. The mesh constructor positions constrained vertices on or near a plurality of non-coplanar delineation contours defined using the contouring interface.
    Type: Grant
    Filed: January 13, 2014
    Date of Patent: April 21, 2015
    Assignee: Koninklijke Philips N.V.

  • Efficient user interaction with polygonal meshes for medical image segmentation
    Patent number: 8660325
    Abstract: An apparatus for delineating a structure of interest includes: a plane selection interface (32, 70) for selecting a contouring plane of selectable orientation in a three-dimensional image or map (80); a contouring interface (32, 72) for defining a contour in the selected contour plane; and a mesh constructor (74, 76) configured to construct a three-dimensional polygonal mesh (90) delineating the structure of interest in the three-dimensional image or map. The mesh constructor positions constrained vertices (102, Vc) on or near a plurality of non-coplanar delineation contours (84, Ccor, Cobl) defined using the contouring interface.
