The influence of preprocessing of CT images on airway tree segmentation using 3D region growing

In this paper problem of airway tree segmentation from CT data sets was regarded. The idea of segmentation using 3D seeded region growing algorithm was introduced. Common problems arising during extracting airway tree from CT data using region growing method were explained. Especially problem of leakage from airway into the lung parenchyma was outlined. Common methods of CT data sets preprocessing were tested in order to check their influence on quality of image segmentation using region growing. Results were presented and discussed.
