用混合分割方法估计孤立性肺结节直径

Estimation of solitary pulmonary nodule diameters with a hybrid segmentation approach
摘要：
A method for estimating a diameter of an object of interest, includes extracting a sub-volume of voxels around a marker identifying a location of the object of interest, and determining a segmentation result identifying an edge of the object of interest by a reactive-diffusion method. The method further includes performing a boundary check on the segmentation result to determine whether the object of interest is solitary, estimating a diameter of the object of interest from the segmentation result upon determining the object of interest to be solitary, and extracting the object of interest by performing ellipsoid fit on the sub-volume and estimating a diameter of the object of interest upon determining the object of interest to be non-solitary.
摘要（中）：

一种用于估计感兴趣对象的直径的方法，包括提取识别感兴趣对象的位置的标记周围的体素的子体积，以及通过反应扩散来确定识别感兴趣对象的边缘的分割结果 方法。 所述方法还包括对所述分割结果执行边界检查以确定所述感兴趣对象是否是孤立的，在确定感兴趣的对象是单独的时，从所述分割结果估计所述对象的直径，以及提取所述感兴趣的对象 通过在子体积上执行椭圆体拟合并且在确定感兴趣的对象是非孤立性时估计感兴趣对象的直径。
