| Abstract(in English) | This paper presents a new system for detecting lung nodules on digital chest x-ray image. The proposed system consists of four processing steps. They are the location of lung nodule candidates by using adaptive ring filter, the extraction of their regions, the extraction of feature parameters, and the discrimination between the normal and the abnormal regions by using maximum-likelihood method. In the preliminary experiments, fifty six features were evaluated using ROC analysis and eight of them were selected. Furthermore the experiments showed that the output image of the adaptive ring filter and the differential image of the original one contain effective information on the difference between the normal and the abnormal regions. The system performance was evaluated using 247 chest radiographs. The experimental results show that the area under ROC curve of the proposed system is 0.82 and its sensitivity and the average number of false positives per image are 80% and 5.2 respectively. These experimental results show the effectiveness of the proposed system. |
