A SYSTEM AND METHOD FOR DIAGNOSING PANCREATIC INTRAEPITHELIAL NEOPLASIA

摘要

PURPOSE: A system for diagnosing a pancreatic intraepithelial neoplasia is provided to easily separate an interest region like a lumen and a nucleus from a tissue image by using a region growing technique and maximum entropy thresholding technique. CONSTITUTION: A tissue image input unit(110) provides a tissue image. A preprocessor(120) separates a lumen and a nucleus by preprocessing the tissue image and includes a lumen separating unit(121) and a nucleus separating unit(122). A feature extracting unit(130) extracts morphological features from the separated lumen and nucleus. A diagnosing unit(140) classifies a pancreatic intraepithelial neoplasia according to a stage of cancer.
