Abstract

Extraction of inter lobar fissure is an active study for diagnosis and treatment. However, lung diseased cases have problems. The proposed method covers diseased cases, and contains three phases of coarse extract, fine extract and correction, using behavior of membrane. We applied this method to normal and lung diseased cases. Rate (average±standard eviation) of gold standard within 2 mm of extraction result were 91.2±3.6% for normal, and 89.7±4.9% for lung diseased cases. Rate of extraction result within 2 mm of gold standard for normal cases were 95.5±3.7%, and 93.6±4.8% for lung diseased.
