Current methods for the assessment of airway wall work well in idealized models of the airway. We propose a new method for airway wall detection based on phase congruency. This method does not rely on either a specific model of the airway or the point spread function of the scanner. Our results show that our method gives a better localization of the airway wall than "full width at a half max" and is less sensitive to different reconstruction kernels and radiation doses.}, author = {San Jose Est{\'e}par, Ra{\'u}l and Washko, George G and Silverman, Edwin K and Reilly, John J and Kikinis, Ron and Westin, Carl-Fredrik} }
