Fiber optic ultrasound generator and detector for high resolution ultrasound imaging

点击翻译按钮获取中文摘要

Ultrasound systems are the most commonly used equipment in medical settings for diagnosis or internal**observation of bio-tissues in real-time. However, the imaging potential of these equipment is surprisingly**currently quite limited due to technical constraints. Therefore, to counterpart these limitations, doctors have no**other choices than to direct their patients towards other potentially harmful and more expensive imaging**systems, such as XRays. This research proposal aims at pushing back many of these technical limitation by**developing a fiber-optic high-frequency ultrasound generation and detection system for ultrasonic and**photoacoustic imaging. Our results will help develop a more flexible ultrasound system with higher image**resolution, smaller captor size, easier and larger calibration options for application in a variety of settings and**places such as internal tissues or organs. Working with two industrial partners, who are well positioned for**applicability and distribution of the potential product, this collaboration offers a unique chance to quickly**develop a well-designed product and to distribute it widely. One of the expected outcome of this research is a**novel biomedical imaging modality to be used, for instance, in Intensive Care Units Sonology for diagnosis and**treatment guidance. The proposed research will design a graphene-coated nanofiber device, to be used as a**high-frequency ultrasound generator. Note that together, our research team and collaborators, we gather an**unique mix of expertise that are required to successfully complete this proposed research, and to position**Canada as a leader in biomedical ultrasound imaging technics, as well as high frequency ultrasound generation**and detection techniques. Four graduate students and one postdoctoral fellow will participate in this project and**therefore benefit from a multidisciplinary and highly qualifying training in academia and industry settings.**************
