The proportion of the solid part portion in a GGO nodule is one of features to detect lung cancer. It is difficult to segment the solid part in a GGO nodule completely because tissues surrounding GGO nodules include some impurities like noises in image processing technology. This paper proposes Active Contour Model (ACM) to find the boundary of a GGO nodule because ACM algorithm can remove noises. The size of a GGO nodule can be computed based on the boundary of the GGO nodule. Expectation-Maximization (EM) algorithm can segment the no solid part in GGO nodules because no solid part and solid part have different densities. Experiments show ACM algorithm is more effective than EM algorithm to find the boundary of a GGO nodule. Moreover, our proposal also can reduce the burden of doctors because it can find the boundary of GGO nodules automatically.
