Abstract (in Japanese) (See Japanese page) 
(in English) Recently, in diagnosis of pulmonary embolism and pulmonary tumor, CT images are used mainly. In the diagnosis of pulmonary embolism and pulmonary tumor, the kind of pulmonary vessels is important information. But, it is impossible to distinguish easily between pulmonary arteries and pulmonary veins, because there are not differences of pulmonary arteries and pulmonary veins on CT values. Moreover, in the improvement for performance of CT apparatus, the number of slices of CT images increase. So, it has become the burdens of the radiologist. We have developed an computer aided diagnosis system for classifying pulmonary arteries and pulmonary veins automatically for decreasing the burden of the radiologist.
As stated above, pulmonary blood vessels can’t be classified easily by a threshold processing. In this study, we make use of the relation that pulmonary arteries are in parallel to the bronchial tubes and that pulmonary veins run between the bronchial tube and the bronchial tube. We measure the distance of pulmonary vessels from each amount of characteristic ( bronchial tubes , boronoi boundary ), pulmonary arteries and pulmonary veins are classified based on the distance information and that result was visually evaluated.
