全光超声成像是一种新兴的电子超声成像技术,它利用光来产生和检测超声。到目前为止,Aous成像一直使用要么导致采集时间较长的范例,要么使用临床不切实际的台式成像系统。在这项工作中,我们提出了一种新的Aous成像范例,其中使用扫描光学来快速合成成像孔径。这一范例使第一个Aous系统能够使用灵活的手持成像探头,这代表着迈向临床转换的关键一步。这种探头提供了视频率成像和实时显示,并通过模型和活体人体组织进行了演示。Erwin J Alles,Eleanor C Mackle,Sacha Noimark,Edward Z Zhang,Paul C Beard,Adrien E Desjardins
All-optical ultrasound (AOUS) imaging, which uses light to both generate and detect ultrasound, is an emerging alternative to conventional electronic ultrasound imaging. To date, AOUS imaging has been performed using paradigms that either resulted in long acquisition times or employed bench-top imaging systems that were impractical for clinical use. In this work, we present a novel AOUS imaging paradigm where scanning optics are used to rapidly synthesise an imaging aperture. This paradigm enabled the first AOUS system with a flexible, handheld imaging probe, which represents a critical step towards clinical translation. This probe, which provides video-rate imaging and a real-time display, is demonstrated with phantoms and in vivo human tissue.
