太赫兹成像和光谱在医疗领域的应用综述

Application of terahertz imaging and spectroscopy in medical field

在医疗领域中,人们对于太赫兹成像与光谱的研究早已不再停留于几年前的基础研究了,而是深入到了以组织、细胞、皮肤成像以及中医药学检测分析等的集中研究。相比传统意义上的医疗手段,如超声波、X光、核磁共振及红外线等,太赫兹波技术具有更加显著的优势,主要体现在宽带光谱分析能力强、分辨率高及耗能低等方面。围绕着太赫兹成像和光谱技术,主要对太赫兹技术在生物医学和中医药学方面的应用分别进行阐述,分析了其在人体皮肤组织、肿瘤、骨密度、癌症以及中草药方面应用的现状和发展,并在此基础上,提出此阶段所面临的各种问题,并对今后太赫兹发展做出展望。基于上述的研究进展为太赫兹成像和光谱技术在医疗领域的应用奠定了基础。

In the medical field,the research on terahertz imaging and spectroscopy is no longer the basic research of a few years ago,but the intensive research on tissue,cell,skin imaging and TCM detection and analysis.Compared with traditional medical means,such as ultrasound,X-ray,NUCLEAR magnetic resonance and infrared ray,Terahertz wave technology has more significant advantages,mainly reflected in strong broadband spectral analysis ability,high resolution and low energy consumption.In this paper,the application of Terahertz technology in biomedicine and traditional Chinese medicine is reviewed,and the status and development of terahertz technology in human skin tissues,tumors,cancers and Chinese herbs are analyzed.Based on the above research progress,terahertz imaging technology has laid a foundation for its application in the medical field.
