Methods have recently been developed that make use of electromagnetic radiation at terahertz (THz) frequencies, the region of the spectrum between millimetre wavelengths and the infrared, for imaging purposes. Radiation at these wavelengths is non-ionizing and subject to far less Rayleigh scatter than visible or infrared wavelengths, making it suitable for medical applications. This paper introduces THz pulsed imaging and discusses its potential for in vivo medical applications in comparison with existing modalities.
最近已开发出一些方法，利用太赫兹（THz）频率的电磁辐射（毫米波波长和红外线之间的光谱区域）进行成像。这些波长的辐射是非电离的，并且与可见光或红外线波长相比，受到的瑞利散射要少得多，因此适用于医学应用。本文介绍了太赫兹脉冲成像，并与现有模式相比，讨论了其在体内医学应用中的潜力。
