Automatic Lever Tumor Detection from CT

摘要

This paper proposes an automatic system which can perform the entire diagnostic process from the ex- traction of the liver to the recognition of a tumor. In particular, the proposed technique uses shape information to identify and recognize a lesion adjacent to the border of the liver, which can otherwise be missed. Because such an area is concave like a bay, morphological operations can be used to find the bay. In addi- tion, since the intensity of a lesion can very greatly according to the patient and the slice taken, a decision on the threshold for ex- traction is not easy.
