摘要

PPROBLEM TO BE SOLVED: To provide a system and a method realizing associated visualization to localize abnormalities in a system and a method for automated airway evaluation using an airway lumen diameter, an airway wall thickness and a broncho-arterial ratio. PSOLUTION: A bronchial tree is segmented, the segmented bronchial tree is modeled, and a first ratio which is a ratio between the diameter of the airway lumen and the diameter of an artery accompanying the airway in the segmented and modeled bronchial tree is computed or a second ratio which is a ratio between the diameter of the artery and a thickness of the airway wall is computed, or a tapering index which indicates a tapering of the diameter of the airway lumen is computed. The first ratio, second ratio or tapering index is scored and color-coded, and the segmented, modeled and color-coded bronchial tree is visualized according to the first ratio, second ratio or tapering index.

解决方案：分割支气管树，对分割后的支气管树进行建模，在分割后建模的支气管树中，第一比率为气道内腔直径与伴随气道的动脉直径之比。计算第二比率，或者计算第二比率，该第二比率是动脉的直径与气道壁的厚度之间的比率，或者计算出表示指数的气道内腔直径的渐缩指数。对第一比率，第二比率或渐缩指数进行评分和颜色编码，并根据第一比率，第二比率或渐缩指数可视化经分段，建模和颜色编码的支气管树。
