摘要
光声层析成像(PAT)作为一种新兴的成像技术,以独特的免标记、高分辨率、高对比度的多尺度成像能力,在生物医学成像中备受关注,正迅速向临床试验转化。得益于超声探测技术和激光技术的快速发展,PAT系统正逐步实现实时、大视场、高分辨率、高穿透深度的组织结构和功能成像。主要综述了环形阵列式PAT系统在生物医学成像中的研究进展及其在预临床和临床实践中面对的问题。
Abstract
As a new imaging technology, photoacoustic tomography (PAT) has attracted more and more attention in biomedical imaging due to its unique multi-scale imaging abilities of label-free, high resolution and high contrast, and has been rapidly transformed into clinical trials. Benefitting from the rapid development of ultrasonic detection technology and laser technology, the PAT system has gradually achieved real-time, large field of view, high resolution and high penetration depth of tissue structure and functional imaging. In this paper, we mainly summarize the advances of the circular array PAT system in biomedical imaging and the problems it faces in preclinical and clinical practices.
