项目摘要

Micro-resolution ultrasound imaging has emerged in the past two decades as a new non-invasive tool forassessing structural and functional details of living tissues in fine scale. It is nowadays possible to use thisimaging tool to map cardiovascular dynamics through an operating mode known as color flow imaging (basedon Doppler ultrasound principles). However, this mode can provide limited insights on blood flow dynamicsinside the circulation. There is a need for engineering innovations that can enhance the quality of blood flowvisualization in micro-ultrasound.In this project, initial efforts will be dedicated to develop color encoded speckle imaging (CESI) as a newcardiovascular imaging mode for micro-ultrasound. CESI is a new flow visualization algorithm that offersduplex rendering of flow trajectory (highlighted by flow speckle motion) and flow speed (depicted throughDoppler-based velocity color coding). Over the project period, proof-of-concept implementation of CESI formicro-ultrasound will be pursued, and flow phantom experiments will be conducted to test its performance. Itis anticipated that the feasibility of realizing CESI as a new micro-ultrasound flow imaging mode will beestablished by the end of this project. Such technical endeavor will economically benefit Canada bystrengthening the country's position as a global leader in micro-ultrasound imaging.
微分辨率超声成像技术是近二十年来兴起的一种新的无创性工具,可以对活体组织的结构和功能细节进行精细的评估。现在可以使用这种成像工具,通过一种称为彩色血流成像(基于多普勒超声原理)的操作模式来绘制心血管动力学。然而,这种模式可以提供有限的见解血液循环内的流动动力学。本项目的主要研究内容是彩色编码散斑成像(color encoded speckle imaging,CESI),它是一种新的心血管微超声成像模式。CESI是一种新的流场可视化算法,它提供了流场轨迹(通过流场散斑运动突出显示)和流场速度(通过基于多普勒的速度颜色编码描述)的双重绘制。在项目期间,将继续实施CESI微型超声的概念验证,并将进行流动体模实验以测试其性能。预计到本项目结束时,将建立实现CESI作为一种新的微超声血流成像模式的可行性。这种技术奋进将使加拿大在经济上受益,加强该国作为微型超声成像全球领导者的地位。
