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.

Efficient user interaction with polygonal meshes for medical image segmentation

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 (, Vc) on or near a plurality of non-coplanar delineation contours (, Ccor, Cobl) defined using the contouring interface.
