摘要
与红外辐射、X射线、核磁共振、超声波等传统医疗诊断技术相比, 太赫兹技术具有能量低、空间分辨力高和带宽宽等独特分析能力, 成为人体成像或人体组织癌症诊断技术的补充技术。分别对肝脏和肺的正常组织与肿瘤组织做了太赫兹光谱检测与太赫兹成像研究, 通过肝脏的光谱检测与成像实验总结出相关经验, 使得肺癌组织太赫兹成像得到了明显的效果, 并且发现肺癌肿瘤组织在1.0 THz~1.75 THz频率范围内的太赫兹成像能够明显区分出正常组织与肿瘤组织, 且频率越高, 成像分辨力越高。
Abstract
Compared with traditional medical diagnostic technologies, infrared radiation, X-rays, nuclear magnetic resonance and ultrasound, etc, terahertz technology has become the complementary technology of human imaging or human tissue cancer diagnosis due to its low energy, high spatial resolution and unique analysis ability. Using Terahertz-Time Domain Spectrum(THz-TDS) and terahertz imaging technology, the normal and tumor tissues of the liver and lung are imaged respectively. Based on the relevant experiences from the terahertz spectral detection and imaging measurements of liver, significant results about the terahertz imaging of lung cancer tissue in the range of 1.0 THz-1.75 THz are obtained. The normal and tumor tissues can be clearly distinguished by the point-to-point terahertz pulse imaging; and the higher the selected frequency within the range, the higher imaging resolution can be achieved.
