摘要

研究了从胃癌患者身上获得的新鲜切除组织样本。样本分为癌变区、正常区和病理改变区。利用反射模式下的太赫兹时域光谱(THz-TDS)研究了它们的光学特性和光谱特征。发现正常组织和癌组织反射信号的波形及其光学性质有很好的区别，因此可以认为利用太赫兹- tds区分胃癌组织和正常组织是可能的。

Gastrointestinal cancer diagnostics by terahertz time domain spectroscopy

Samples of fresh excised tissues obtained from patients who had undergone gastric cancer have been investigated. Samples consisted of cancer zone, normal zone and pathologically changed zone. Their optical properties and spectral features were investigated by terahertz time-domain spectroscopy (THz-TDS) in reflection mode. It was found that waveforms of reflected signals from normal and cancer tissues and their optical properties were well distinguished, so it can be concluded that it is possible to discriminate gastric cancer tissue from normal by using THz-TDS.
