| Abstract(in English) | This paper presents a method to analyze volume evolutions of pulmonary nodules for discrimination between malignant and benign nodules. Our method consists of four steps; (1) The 3-D rigid registration of the two successive 3-D thoracic CT images, (2) the 3-D affine registration of the two successive region-of-interest (ROI) images, (3) non-rigid registration between local volumetric ROIs, and (4) analysis of the local displacement field between successive temporal images In preliminary study, the method was applied to the successive 3-D thoracic images of two pulmonary lesions including a metastasis malignant case and a inflammatory benign to quantiry the evolving process in the pulmonary nodules and surrounding structure. These experimental results indicate that our method is a promising tool to quantiry how the lesions evolve their volume and surrounding structures. |
