Micro-resolution ultrasound imaging has emerged in the past two decades as a new non-invasive tool forx000D
assessing structural and functional details of living tissues in fine scale. It is nowadays possible to use thisx000D
imaging tool to map cardiovascular dynamics through an operating mode known as color flow imaging (basedx000D
on Doppler ultrasound principles). However, this mode can provide limited insights on blood flow dynamicsx000D
inside the circulation. There is a need for engineering innovations that can enhance the quality of blood flowx000D
visualization in micro-ultrasound.x000D
In this project, initial efforts will be dedicated to develop color encoded speckle imaging (CESI) as a newx000D
cardiovascular imaging mode for micro-ultrasound. CESI is a new flow visualization algorithm that offersx000D
duplex rendering of flow trajectory (highlighted by flow speckle motion) and flow speed (depicted throughx000D
Doppler-based velocity color coding). Over the project period, proof-of-concept implementation of CESI forx000D
micro-ultrasound will be pursued, and flow phantom experiments will be conducted to test its performance. Itx000D
is anticipated that the feasibility of realizing CESI as a new micro-ultrasound flow imaging mode will bex000D
established by the end of this project. Such technical endeavor will economically benefit Canada byx000D
strengthening the country's position as a global leader in micro-ultrasound imaging.
