针对14张脑瘤（ Positron Emission Tomogrophy ，PET）图像切片，将感兴趣区域分割出来，利用积分原理计算其体积特征．首先提取出图片所有点的像素值，然后利用自组织神经网络将像素值进行分类，其中自组织神经网络的输入节点经过多次的试验确定为2×2．通过自组织神经网络，可以将各个元素点进行标志，使得图片的分离简单精确并且计算出目标区域的元素点数．最后通过Matlab对14个切片构建出目标区域的三维立体图，利用积分原理算出该目标区域的体积为9.9 cm3．该方法合理，计算结果有效，且计算结果可对临床诊断有辅助作用．

A case study was conducted of the slicing of 14 cerebroma PET images , of which interesting parts were divided , with a calculation of their volume features followed .Firstly, all pixels in these images were extracted , and then classified according to the self-organizing neural network , the input node of which was determined as 2 ×2 through repeated experiments .By marking each element point through the self-organizing neural network , it is easier and more accurate to extract images and to calculate the num-ber of elements within the target zone .With the use of Matlab , it built the three-dimension chart of the target zone within the 14 slicings.Finally, the volume of target areas was calculated by using the integral principle .Experimental results show this theory is a plausible one with effective outcome , which can offer assistance in clinical diagnosis .
