VISUALIZATION AND CHARACTERIZATION OF PULMONARY LOBAR FISSURES
First Claim
1. A system for visualizing pulmonary fissures of a person'"'"'s lungs comprising;
- a processor;
software comprising instructions for the processor for creating a visual display comprising the 3 dimensional model of the pulmonary fissures,wherein creating a visual display comprising a 3 dimensional model of the pulmonary fissures comprises;
accessing volumetric imaging data of the person'"'"'s lungs;
analyzing the volumetric imaging data to segment the lungs into lobes;
using the segmented lobes, identifying locations at which pulmonary fissures should be present as the locations where the lobes abut each other;
analyzing the volumetric images to identify locations at which pulmonary fissures are present as existing fissure,comparing the identified locations at which pulmonary fissures should be present to the identified locations at which pulmonary fissures are present to identify locations of missing fissure; and
creating a visual display comprising a 3 dimensional model of the pulmonary fissures comprising existing fissure portions and missing fissure portions, wherein the existing fissure portions are visually distinct from the missing fissure portions.

Abstract
Systems and methods for visualizing pulmonary fissures including a processor and software instructions for creating a 3 dimensional model of the fissures. Creating the 3 dimensional model includes accessing volumetric imaging data of the patient'"'"'s lungs, analyzing the volumetric imaging data to segment the lungs into lobes, using the segmented lobes to identify locations at which pulmonary fissures should be present where the lobes abut each other, analyzing the volumetric images to identify locations at which pulmonary fissures actually are present as existing fissure, comparing the locations at which pulmonary fissures should be present to the locations at which pulmonary fissures are present to identify locations of missing fissure, and creating a visual display comprising a 3 dimensional model of the pulmonary fissures including existing fissure portions and missing fissure portions, with the existing fissure portion visually distinct from the missing fissure portions.
