Modeling of airway in 4D lung CT images

Lung cancer is a disease that consists of uncontrolled cell growth in tissues of the lungs. There are a number of different treatment options available for lung cancer. Radiation therapy is a process in which high energy radiation is applied to kill cancer cells and shrink tumors. A treatment plan of patient is developed before radiation therapy in which the clinician spent a lot of time on manually marking the airways on the CT scan images so that airways can be protected while doing the radiotherapy. Work in this paper is a step towards automating the airway segmentation.
