Computerized tomographic angiography image segmentation for 3D-volume reconstruction
Yun Liang, Robert A. Kruger · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1994
A computerized scheme for the automated segmentation of contrast enhanced arteries is developed for computerized tomographic angiography (CTA) data. Segmentation is performed with two-dimensional (2D) images on a slice-by-slice base. Image processing techniques include gray-level thresholding, eight-point connectivity tracking, region growing, moment analysis and morphological erosion. The results enable the generation of separated three-dimensional (3D) displays of both vascular and non-vascular structures. The method has been applied to several clinical cases and has shown great promises.
