However,since there exist some similarities between the lung’s flank outline area and the rib contours,we can find the growth points of suspicious nodules more precisely by using cubic spline to fit the rib contours at first,then apply regional growth to the combined lung contour image and the rib contour image.
利用肋骨轮廓与肺区轮廓形状相似的特性,先用三次立方样条曲线拟合出肋骨的内部轮廓,然后根据肋骨轮廓图与肺区轮廓图找出可疑粘连肿瘤的种子点,最后将肋骨轮廓图与肺区图相结合进行区域生长找到疑似粘连肿瘤。
