摘要
Automatic extraction of the pulmonary emphysema area on 3-D chest CT images was performed based on an adaptive thresholding technique and we proposed a method to estimate the ratio of emphysema area within whole lung volume. We employed 32 cases (15 normal and 17 abnormal) previously diagnosed by radiologists, the ratio of all normal cases were less than 2%, and that of abnormal cases ranged from 1% to 26%. It was concluded that the effectiveness of our approach was confirmed in this initial work. (C) 2003 Published by Elsevier Science B.V.
