Title:
EXTRACTING BULLOUS EMPHYSEMA AND DIFFUSE EMPHYSEMA IN E.G. CT VOLUME IMAGES OF THE LUNGS
Document Type and Number:
WIPO Patent Application WO/2013/140374
Kind Code:
A3
Abstract:
An processor (118) includes a bullous emphysema identifier (206) that processes voxels of the volumetric image data and identifies voxels corresponding to bullous emphysema, a two dimensional projection image generator (206) that generates a 2D bullous emphysema projection image based on the voxels corresponding to bullous emphysema, wherein an intensity of a contour of a bulla in the 2D bullous emphysema projection image is based on a size of the bulla, and a feature highlighter (210) that highlights the bullous emphysema in the 2D bullous emphysema projection image using second first indicia.
