太赫兹电磁波的穿透特性与其应用密切相关。我们使用了太赫兹波谱系统，它很容易穿透一些不含水的材料，例如，塑料和陶瓷。该系统的开发有多种用途，包括测量半导体和生物材料的特性，以及在机场检测塑料炸弹和陶瓷刀。它也用于医学成像系统，如磁共振成像（MRI），在一些研究机构。它不仅可以显示出振幅的差异，而且还可以显示出样本各点的相位差异。MRI技术通常使用造影剂来增强图像质量。二亚乙基三胺五乙酸钆（Gd-DTPA）是由重金属离子制成的，通常用作临床MRI造影剂。氧化钆（Gd 2 O3）纳米粒子是一种新型的造影剂。它的作用是用抗体或配体装备每个粒子的核心。它可以在血管中自由循环，而不会在肝脏或肺部积聚。本研究显示氧化钆奈米粒子的特性可进一步提升太赫兹医学影像，太赫兹电磁波的穿透特性与其应用相关。我们使用了太赫兹波谱系统，它很容易穿透一些不含水的材料，例如，塑料和陶瓷。该系统的开发有多种用途，包括测量半导体和生物材料的特性，以及在机场检测塑料炸弹和陶瓷刀。它也用于医学成像系统，如磁共振成像（MRI），在一些研究机构。它不仅可以显示出振幅的差异，而且还可以显示出样本各点的相位差异。MRI技术通常使用造影剂来增强图像质量。二亚乙基三胺五乙酸钆（Gd-DTPA）是由重金属离子制成的，通常用作临床MRI造影剂。氧化钆（Gd 2 O3）纳米粒子是一种新型的造影剂。它的作用是用抗体或配体装备每个粒子的核心。它可以自由地循环，
The penetration property of the terahertz electromagnetic (THz) wave is relevant to its use. We used the THz wave spectroscopy system which easily penetrates some materials that do not contain water, e.g., plastic and ceramics. The system has been developed for several purposes, including measuring the properties of semiconductors and bio‐materials, and detecting plastic bombs and ceramic knives at airports. It is also used for medical imaging systems, such as magnetic resonance imaging (MRI), at some research institutes. It can show not only the difference in amplitude, but also the difference of the phase of each point of sample. MRI technology usually uses contrast agents to enhance the quality of the image. Gadolinium diethylenetriamine pentaacetic acid (Gd‐DTPA), made with a heavy metal ion, is commonly used as a clinical MRI contrast agent. Gadolinium oxide (Gd2O3) nanoparticle is a new contrast agent. It serves to equip the core of each particle with antibodies or ligands. It can freely circulate in blood vessels without amassing in the liver or lungs. This study shows the characteristics of gadolinium oxide nanoparticles to further advance terahertz medical imaging.The penetration property of the terahertz electromagnetic (THz) wave is relevant to its use.
