1) 3-D lung nodule
三维肺结节
1.
Based on the K-L transform and support vector machine,a new recognition algorithm for the 3-D lung nodule was presented to solve the problem that the details of lung nodule were often ignored in the 3-D space when extracting the characteristics of lung nodule in the interested area by the conventional 2-D method.
首先对三维肺结节的几何特征和密度特征进行分析,计算并提取三维特征形成原始特征空间,然后使用K-L变换方法进行原始空间变换,去除特征间相关性,最后采用支持向量机分类方法来进行肺结节识别,并引入ROC曲线对算法性能进行评价。

补充资料：肺内孤立结节
肺内孤立结节
影像学术语。X线检查中显示的肺内＜4cm的类圆形病灶，无肺不张、肺炎、卫星病灶和局部淋巴结肿大。高分辨率CT(HRCT)显示结节内有均匀低密度区者主要见于良性病变，结节内有非均匀的低密度区者主要见于恶性病变。这些低密度区包括：①空洞。②含气的支气管。③坏死。良性结节的特征是：①结节的边缘光滑，有轻度分叶，无毛刺。②结节的中心有条状或弥漫性钙化，至少占横断面的10%。③钙化至少在两个连续薄层层面上出现。恶性结节的钙化是非中心、细小的条状，钙化的范围小于结节的10%。CT增强扫描中，恶性结节强化行为明显于良性结节。
