The objective of the proposed research is to develop a high performance Microelectromechanical systems (MEMS) based ultrasonic probe for 2-D and 3-D anatomical and functional medical diagnostic imaging using recently patented advances made in Capacitive Micromachined Ultrasonic Transducer (CMUT) technology at the University of Windsor (UW). This new technology is based on a patented, "Cyclotene® based wafer bonding and sealed cavity formation", technique developed by the applicant at the University of Windsor. This new technique enables one to fabricate highly compact, low cost CMUT arrays with better transduction efficiency and has been licensed for automotive applications to MIS Electronics, a Toronto based company. The aim of the proposed project is to exploit the capabilities of this new technique to realize a CMUT based ultrasonic probe that can be used with standard medical diagnostic imaging equipment to produce brighter and higher resolution images as compared to conventional piezoelectric based ultrasonic scanners. The target probe will also have the potential to be configured or fabricated to offer continuous wave (CW) high pressure focused ultrasound (HIFU) for use in therapeutic applications, such as cancerous cell ablation. The global research trend is to switch from piezoelectric ultrasonic transducers to CMUTs for medical imaging and therapeutic applications for improved diagnostic image quality, faster healing, and less invasive treatment at a lower cost and also to offer ultrasound based new healthcare technologies. The goal of this project is to align this newly developed Canadian CMUT technology with the global trend to exploit the underlying commercial and better healthcare benefit. Successful commercialization of this proprietary leading edge technology will benefit Canada in terms of new manufacturing facilities, creating revenues, new job opportunities and exports. Canada's own healthcare system would also benefit from the outcome of this project as these better performing and lower cost systems would enable more accurate diagnosis and therapy.

拟议的研究的目的是开发一个高性能的微机电系统（MEMS）为基础的超声探头的2-D和3-D解剖和功能的医疗诊断成像使用最近专利的进步在电容式微机械超声换能器（CMUT）技术在温莎大学（UW）。这项新技术是基于申请人在温莎大学开发的专利技术“基于Cyclotene®的晶圆键合和密封腔形成”。这种新技术使人们能够制造高度紧凑，低成本的CMUT阵列，具有更好的转换效率，并已被授权用于汽车应用的MIS电子，多伦多的公司。拟议项目的目的是利用这种新技术的能力，实现基于CMUT的超声探头，该探头可与标准医疗诊断成像设备一起使用，与传统的基于压电的超声扫描仪相比，可产生更明亮和更高分辨率的图像。目标探针还将具有被配置或制造成提供连续波（CW）高压聚焦超声（HIFU）以用于治疗应用（诸如癌细胞消融）的潜力。全球的研究趋势是从压电超声换能器转向CMUT，用于医学成像和治疗应用，以提高诊断图像质量，更快愈合，以更低的成本进行微创治疗，并提供基于超声的新医疗保健技术。该项目的目标是使这种新开发的加拿大CMUT技术与全球趋势保持一致，以利用潜在的商业和更好的医疗保健效益。这项专有的前沿技术的成功商业化将使加拿大在新的制造设施、创造收入、新的就业机会和出口方面受益。加拿大自己的医疗保健系统也将受益于这一项目的成果，因为这些性能更好、成本更低的系统将能够实现更准确的诊断和治疗。
