We construct a microscopic hyperspectral imaging system to distinguish between normal and cancerous gastric cells. We study common transmission-spectra features that only emerge when the samples are dyed with hematoxylin and eosin (H&E) stain. Subsequently, we classify the obtained visible-range transmission spectra of the samples into three zones. Distinct features are observed in the spectral responses between the normal and cancerous cell nuclei in each zone, which depend on the pH level of the cell nucleus. Cancerous gastric cells are precisely identified according to these features. The average cancer-cell identification accuracy obtained with a backpropagation algorithm program trained with these features is 95%.
我们构建了一个微观高光谱成像系统,用于区分正常和癌变的胃细胞。我们研究了仅在样本用苏木精和伊红(H&E)染色时才会出现的常见透射光谱特征。随后,我们将获得的样本可见光谱分为三个区域。在每个区域中,正常和癌细胞核的光谱响应呈现出明显特征,这些特征取决于细胞核的pH值。根据这些特征可精确识别出癌变的胃细胞。使用基于这些特征训练的反向传播算法程序获得的癌细胞识别平均准确率为95%。
