We have investigated the feasibility of THz time-domain reflectometry for the discrimination of human early gastric cancer (EGC) from the normal gastric region. Eight fresh EGC tissues, which were resected by endoscopic submucosal dissection, were studied. Of them, six lesions were well discriminated on THz images and the regions well correlated with tumor regions on pathologically mapped images. Four THz parameters could be suggested for quantitative discrimination of EGCs.
我们研究了太赫兹时域反射术用于区分人类早期胃癌（EGC）与正常胃区域的可行性。研究了8个通过内镜黏膜下剥离术切除的新鲜EGC组织。其中，6个病变在太赫兹图像上得到了很好的区分，且这些区域与病理映射图像上的肿瘤区域相关性良好。可以提出4个太赫兹参数用于EGC的定量鉴别。
