An interactive extraction of pulmonary nodules and analysis based on dynamic CT Images

摘要

This paper presents a computerized classification scheme of pulmonary nodules in contrast enhanced dynamic CT images. Conventionally, we extracted 3-D nodule images by using a 3d deformable surface model. However, there was a limit in segmenting the 3-D nodule images contacted with vessels and bronchi. We corrected the extracted region by interactive method. We demonstrate how the extraction accuracy affects the classification accuracy of our scheme.
