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.**************

超声系统是医疗环境中最常用的设备，用于诊断或实时观察生物组织。然而，由于技术限制，这些设备的成像潜力令人惊讶 ** 目前相当有限。因此，为了应对这些限制，医生没有其他选择，只能将患者引导到其他可能有害且更昂贵的成像系统，如X射线。本研究提案旨在通过 ** 开发用于超声和 ** 光声成像的光纤高频超声发生和检测系统来克服这些技术限制。我们的研究结果将有助于开发一种更灵活的超声系统，具有更高的图像分辨率，更小的捕获器尺寸，更容易和更大的校准选项，适用于各种设置和位置，如内部组织或器官。与两个工业合作伙伴合作，他们在潜在产品的适用性和分销方面处于有利地位，这种合作提供了一个独特的机会，可以快速开发出设计良好的产品并广泛分销。这项研究的预期成果之一是一种新型的生物医学成像模式，例如，在重症监护室的Sonology中用于诊断和治疗指导。这项研究将设计一种石墨烯涂层的超声波装置，用作高频超声波发生器。请注意，我们的研究团队和合作者一起，我们收集了成功完成这项拟议研究所需的 ** 独特的专业知识组合，并将 ** 加拿大定位为生物医学超声成像技术以及高频超声生成 ** 和检测技术的领导者。四名研究生和一名博士后研究员将参加该项目，** 因此将受益于学术界和工业界的多学科和高素质培训。
