Paper Abstract

Quantitative analyses of three-dimensional (3D) micro structures in human lungs can provide detailed information to elucidate pulmonary disease progress. The pulmonary blood vessels, have so far been studied morphologically and functionally from various aspects. However, there are problems with low spatial resolution or limited field of view. In this study, we propose an extraction method for pulmonary blood vessels like to capillary beds. 3D microstructure of vascular systems is visualized by analyzing of high-resolution dual-energy CT images using large-field high-resolution x-ray micro-CT.
