Paper Abstract

In order to improve the diagnosis of lung cancer from chest radiographs, we are developing a computerized scheme for the detection of pulmonary nodules. The computerized scheme is based on a difference-image technique, feature-extraction techniques and a combination of linear and nonlinear filtering methods. In order to improve the sensitivity of the nonlinear filtering method, we investigated various filter parameters. We found that with a combination of two filtering methods, one effective for subtle nodules and the other effective for moderately subtle nodules, sensitivity can be increased by approximately 15% at a given level of specificity.
