| Abstract(in English) | In this article, we propose a method for classifying candidates of tumors detected in PET/CT images and apply the proposed method to prognostic observations. Our method detects bright regions in a PET image as tumors. For improving the performance of the tumor detection, we select a proper threshold for binarizing the image according to location of a body. In addition, we extract a liver and kidneys that accumulate FDG using a probabilistic atlas, and we detect candidates of tumors in a liver region by a specialized method. Subsequently, we sort the detected tumor candidates by the degree of FDG accumulation. We make prognostic observations by comparing a preoperative PET/CT image with apostoperative PET/CT image. This article shows results of the proposed method and discusses the performance. |
