    • A method for grouping airway and artery pairs, includes: computing a two-dimensional (2D) cross-section of an airway; identifying regions of high-intensity in the 2D cross-section; computing a first indicator for each of the high intensity regions, wherein the first indicator is an orientation measure of the high intensity region with respect to the airway; computing a second indicator for each of the high intensity regions, wherein the second indicator is a circularity measure of the high intensity region; computing a third indicator for each of the high intensity regions, wherein the third indicator is a proximity measure of the high intensity region with respect to the airway; summing the first through third indicators for each of the high intensity regions to obtain a score for each of the high intensity regions; and determining which of the high intensity regions is an artery corresponding to the airway based on its score.
    • 一种用于分组气道和动脉对的方法,包括:计算气道的二维(2D)横截面; 识别2D横截面中高强度的区域; 计算每个所述高强度区域的第一指示符,其中所述第一指示符是所述高强度区域相对于所述气道的取向测量; 计算每个高强度区域的第二指示符,其中第二指示符是高强度区域的圆度度量; 计算每个所述高强度区域的第三指示符,其中所述第三指示符是所述高强度区域相对于所述气道的接近度量; 对每个高强度区域的第一至第三指标求和,以获得每个高强度区域的得分; 并且基于其得分确定哪个高强度区域是对应于气道的动脉。
