Abstract

The microwave-induced thermoacoustic imaging (TAI) technology has both the advantages of high contrast of microwave imaging and high resolution of ultrasound imaging (UI), so it has carried out exploratory application research in various areas, such as the early detection of breast tumors and cerebrovascular diseases. However, the microwave generator used in the traditional TAI technology is huge and expensive, and the temporal resolution is also too low due to the single-element scanning mechanism. Thus, it is difficult to meet the needs of clinical applications. In this paper, the iterative process and the analysis of related application scenarios from single-element scanning to portable and array-based TAI, such as the miniaturized microwave generator, handheld antenna, multi-channel data acquisition, and UI/TAI dual-modality imaging, are reviewed, and the future trends of this technology are discussed. This review helps researchers in the field of TAI learn the technological development process and future trends. It also deepens clinicians’ understanding of TAI so as to put forward more application requirements.

热声成像：从单元件扫描到便携式和基于阵列的成像

微波诱导热声成像(TAI)技术兼具微波成像的高对比度和超声成像(UI)的高分辨率优势，在乳腺肿瘤、脑血管疾病的早期检测等多个领域开展了探索性应用研究。然而，传统的TAI技术中使用的微波发生器体积庞大，价格昂贵，而且由于单元素扫描机制，时间分辨率也太低。因此，难以满足临床应用的需要。本文综述了从单元扫描到小型化微波发生器、手持天线、多通道数据采集、UI/TAI双模成像等便携式阵列式TAI相关应用场景的迭代过程和分析，并讨论了该技术的未来发展趋势。这篇综述有助于TAI领域的研究人员了解技术发展过程和未来趋势。也加深了临床医生对TAI的认识，从而提出了更多的应用要求。
