项目摘要

The field of ultrasound is being disrupted as imaging devices get smaller, prices get lower, and markets get larger and more diverse. The fastest growing segment of ultrasound is in pocket-sized devices with prices approaching $2000. Growth has been derived from new, miniature ultrasound-on-a-chip electronics, direct connection to a smartphone, and advanced real-time image processing. As a result, these extremely portable ultrasound devices have the potential to become "ubiquitous ultrasound" as they reach new markets with a wider range of operators. My research has been on improving image acquisition in both 2D and 3D plus improving image quality through new software. Although we have been successful in improving these aspects, it is becoming clearer that barriers to adoption still exist with traditional ultrasound hardware. In particular, ultrasound must be easier to operate. Today, the expertise of the operator is still a critical and limiting factor, so even the latest ultrasound devices are used relatively infrequently compared to their potential usage. Breakthrough research in our lab on ultrasound transducers has the potential to fundamentally change the way ultrasound is operated and greatly expand the use of ultrasound. In particular, we invented a new way of creating ultrasound-on-a-chip that replaces the standard rigid hand-held transducer with a flexible, transparent, wearable patch. This grant will develop new computer algorithms that use these capabilities to help operate ultrasound in new ways, especially in guiding specialized procedures. For example, a flexible, transparent, wearable patch could allow an operator to use both hands to perform a procedure, while at the same time watch the procedure live on the ultrasound image. Enabling ultrasound guidance in this and other related procedures should improve their uptake, speed, accuracy and outcomes. The proposed algorithms will: (1) form high-quality ultrasound images from a flexible transducer; (2) perform tracking and guidance with a transparent transducer; (3) calculate and display image-based guidance using augmented reality; and then we will (4) integrate these algorithms into a usable system that can be objectively tested. The end result will be a set of technologies that enable a new and complementary way of operating ultrasound. These new technologies will open up new applications not only in medical applications but also in non-destructive testing of man-made materials such as flaw detection in manufacturing. This research grant will train 3 PhD, 3 MASc, and 4 BASc in this growing field of ultrasound that Canada enjoys a leading role both in academia and industry. These HQP will gain specific skills in ultrasound signal and image processing plus more general skills in real-time software design, augmented reality and artificial intelligence, all of which are in high demand, in an interdisciplinary, representative, challenging, and welcoming research environment.
随着成像设备变得越来越小、价格越来越低、市场变得越来越大、越来越多样化,超声波领域正在被颠覆。超声领域增长最快的领域是价格接近 2000 美元的袖珍设备。增长源自新型微型片上超声电子设备、与智能手机的直接连接以及先进的实时图像处理。因此,随着这些极其便携的超声设备进入拥有更广泛运营商的新市场,它们有可能成为“无处不在的超声设备”。我的研究方向是改进 2D 和 3D 图像采集,以及通过新软件提高图像质量。尽管我们在这些方面取得了成功的改进,但越来越明显的是,传统超声硬件的采用仍然存在障碍。特别是超声波必须更容易操作。如今,操作员的专业知识仍然是一个关键和限制因素,因此即使是最新的超声设备与其潜在用途相比,使用频率也相对较低。我们实验室对超声换能器的突破性研究有可能从根本上改变超声的操作方式并极大地扩展超声的使用。特别是,我们发明了一种创建超声波芯片的新方法,用灵活、透明、可穿戴的贴片取代标准的刚性手持式传感器。这笔赠款将开发新的计算机算法,利用这些功能帮助以新的方式操作超声,特别是在指导专门程序方面。例如,灵活、透明、可穿戴的贴片可以让操作员使用双手执行手术,同时在超声图像上实时观看手术过程。在该手术和其他相关手术中启用超声引导应该可以提高其采用率、速度、准确性和结果。所提出的算法将:(1)从灵活的换能器形成高质量的超声图像; (2)利用透明传感器进行跟踪引导; (3) 使用增强现实计算并显示基于图像的引导;然后我们将(4)将这些算法集成到一个可以客观测试的可用系统中。最终结果将是一套技术,能够实现一种新的、互补的超声操作方式。这些新技术不仅将在医疗应用中开辟新的应用,而且还将在人造材料的无损检测(例如制造中的缺陷检测)中开辟新的应用。这项研究资助将在加拿大在学术界和工业界处于领先地位的不断发展的超声领域培训 3 名博士、3 名硕士和 4 名学士学位。这些 HQP 将获得超声信号和图像处理方面的特定技能,以及实时软件设计、增强现实和人工智能方面的通用技能,所有这些技能在跨学科、具有代表性、具有挑战性和受欢迎的研究环境中都有很高的需求。
