Abstract

In the continuing development of terahertz technology to enable the determination of tissue pathologies in real-time during surgical procedures, it is important to distinguish the measured terahertz signal from biomaterials and fluids, such as blood, which may mask the signal from tissues of interest. In this paper, we present the frequency-dependent absorption coefficients, refractive indices, and Debye relaxation times of whole blood, red blood cells, plasma, and a thrombus.

摘要

在太赫兹技术不断发展的过程中，为了实现在手术过程中实时确定组织病变，重要的是要将测量的太赫兹信号与生物材料和流体（如血液）区分开来，因为这些生物材料和流体可能会掩盖感兴趣组织的信号。在本文中，我们给出了全血、红细胞、血浆和血栓的频率相关吸收系数、折射率和德拜弛豫时间。
