| Abstract(in English) | In this paper, we propose a method for detecting small nodules (≦ 5mm) from three dimensional chest CT images taken by multi-slice (multi-detector raw) CT scanners. This method suppresses false positive (F.P.) regions by using shape difference between nodule regions and normal structures. Here we introduce a new feature value called, the maximum distance value inside a connected component. This feature value efficiently discriminates nodule regions having spherical shapes and normal structures such as blood vessel and bronchi having cylindrical shapes. We applied the proposed method to four cases of chest CT images. The experimental results showed that the proposed method can reduce the number of F.P. regions drastically in comparison with our previous method. |
