Ultrasound waves are used in a number of applications including sonar, chemical catalysis, non-destructive testing and medicine. We have an active research collaboration in which researchers with complementary expertise are creating breakthrough technologies in the excitation of ultrasonic transducers. Through this effort, we have developed a more efficient method for driving transducers using orthogonal electric fields, which facilitates switching of transducers, making them significantly more efficient. The equipment supported through this research grant will be used to finalize the testing and applications of ultrasound imaging and therapy transducers. We will make use of a unique ultrasound excitation platform that will make it possible to test new techniques for imaging and therapy with flexible and fine control for driving and image reconstruction. The success of this collaborative work combines material science modeling, the design and fabrication of amplifier technology, and device development to bring more affordable, more effective and safer applications of ultrasound to Canadians. We are currently at a critical point in which our promising results require this equipment to collect the data that will drive commercial interest and industrial research collaborations for this technology and the research that supports it. The requested dual driving/receiving system will allow us to test our patented technique by complementing the existing testing capabilities through which this technology was developed. We are currently testing our devices on a short-term lease that will not be sufficient to obtain the data that we require, particularly in light of feedback from potential industrial collaborators that are interested in the technique for complex multi-element imaging prototypes. Devices of this type are not widely available, and there is no equivalent device at Lakehead University or in Thunder Bay. The equipment will be available to all four research teams described in the proposal, for joint projects as well as specific for developments by each team. The main users of the equipment will be students enrolled in the Masters and Ph.D. programs in Electrical and Computer Engineering (ECE) at Lakehead University and will generate data for students enrolled in the graduate programs in Material Sciences at McMaster University. Undergraduate summer students will also benefit from this equipment by working on smaller research projects and obtaining hands-on training. All students trained will gain important experience in the development of multi-element ultrasound devices and signal processing, which is standard in ultrasound imaging industry and for ultrasound therapeutic applications.

超声波有多种应用，包括声纳、化学催化、无损检测和医学。我们开展了积极的研究合作，具有互补专业知识的研究人员正在创造超声波换能器激励方面的突破性技术。通过这项努力，我们开发了一种更有效的方法，使用正交电场驱动传感器，这有利于传感器的切换，使其效率显着提高。这项研究拨款支持的设备将用于完成超声成像和治疗换能器的测试和应用。我们将利用独特的超声激励平台，通过灵活精细的控制驱动和图像重建来测试成像和治疗新技术。这项合作工作的成功结合了材料科学建模、放大器技术的设计和制造以及设备开发，为加拿大人带来了更实惠、更有效和更安全的超声波应用。 我们目前正处于一个关键时刻，我们的有希望的结果需要该设备收集数据，这些数据将推动该技术及其支持研究的商业兴趣和工业研究合作。所要求的双驱动/接收系统将使我们能够通过补充开发该技术的现有测试能力来测试我们的专利技术。我们目前正在以短期租赁的方式测试我们的设备，这不足以获取我们所需的数据，特别是考虑到对复杂多元素成像原型技术感兴趣的潜在工业合作者的反馈。这种类型的设备并未广泛使用，湖首大学或桑德贝也没有类似的设备。该设备将可供提案中描述的所有四个研究团队使用，用于联合项目以及每个团队的具体开发。该设备的主要用户将是硕士和博士生。湖首大学电气和计算机工程（ECE）项目，将为麦克马斯特大学材料科学研究生项目的学生生成数据。本科暑期学生也将通过从事较小的研究项目和获得实践培训而受益于该设备。所有接受培训的学生都将获得多元件超声设备和信号处理开发的重要经验，这是超声成像行业和超声治疗应用的标准。
