Abstract

Recently the diagnoses of dental caries and other dental issues are in a queue as only X-ray-based techniques are available in most hospitals around the world. Terahertz (THz) parametric imaging (TPI) is the latest technology that can be applied for medical applications, especially dental caries. This technology is harmless and thus suitable for biological samples owing to the low energy of THz emission. In this paper, a developed TPI system is used to investigate the two-dimensional (2D) and three-dimensional (3D) images of different samples from human teeth. After analyzing the measured images of the human tooth, the results suggest that the novel THz parametric technology is capable of investigating the inner side structure of the teeth. The technique can be useful in detecting the defects in all types of human and animal teeth. The measurement and analytical calculations have been performed by using the TPI system and MATLAB, respectively, and both are in good agreement. The characteristics of THz waves and their interactions with the tooth samples are summarized. And the available THz-based technologies, such as TPI, and their potential applications of diagnoses are also presented.

用太赫兹技术诊断牙齿问题

最近，由于世界上大多数医院都只有基于x光的技术，龋齿和其他牙齿问题的诊断都排着队。太赫兹(THz)参数成像(TPI)是一项最新的技术，可以应用于医疗应用，特别是龋齿。该技术是无害的，由于太赫兹辐射能量低，因此适用于生物样品。在本文中，开发的TPI系统用于研究人类牙齿不同样品的二维(2D)和三维(3D)图像。通过对人类牙齿的测量图像进行分析，结果表明，这种新型的太赫兹参数化技术能够研究牙齿的内部结构。该技术可用于检测各种类型的人类和动物牙齿的缺陷。利用TPI系统和MATLAB分别进行了测量和分析计算，两者吻合良好。总结了太赫兹波的特征及其与牙齿样品的相互作用。并介绍了基于太赫兹的TPI等现有技术及其在诊断中的应用前景。
