Abstract

This study sought to develop a completely automatic method for image segmentation of the thoracic aorta. We used a total of 4682 images from 10 consecutive patients. The proposed method is based on the use of level set and region growing, automatically initialized using the Hough transform. The results obtained were compared to those of manual segmentation as performed by an external expert radiologist. Concordance between the developed method and manual segmentation ranged from 92.79 to 95.77% in the descending regions of the aorta and from 90.68 to 96.54% in the ascending regions, with a mean value of 93.83% being obtained for total segmentation.

基于水平集和三维区域生长的胸主动脉分割混合方法。

本研究旨在开发一种完全自动化的胸主动脉图像分割方法。我们共使用了来自10个连续患者的4682张图像。该方法基于水平集和区域增长，采用霍夫变换进行自动初始化。所获得的结果与由外部专家放射科医生进行的手动分割进行了比较。该方法与人工分割的一致性在主动脉降段为92.79 ~ 95.77%，在主动脉升段为90.68 ~ 96.54%，总分割的平均值为93.83%。
