| Abstract(in English) | When radiologists encounter a difficult case to diagnose, retrieval of morphologically similar cases in which final diagnosis is established may provide clinically useful information. Existing methods retrieve similar cases for each case in which lesions exist within a certain range of region by calculating similarity for the region specified on a slice image of the query case. However, radiologists diagnose cases of diffuse lung disease (DLD) where lesions appear throughout lungs by observing 3D distribution of lesion textures. We propose a novel method which can retrieve morphologically similar cases based on radiologist’s view for lesion textures and their 3-dimensional (3D) distribution. In our method, we configured a 3D model for central-peripheral regions of a lung and calculated similarity for 3D distribution of lesions using the 3D model. We evaluated the average precision of the proposed method for real CT images, and the experimental result showed that our method improved the accuracy compared with the comparative method. |
