SUMMARY Minimally invasive ultrasound-guided procedures are a mainstay of modern medicine and the number of such procedures continues to grow. Safe, efficient, and precise execution of these procedures requires a clear visualization of the target anatomy and the interventional device (e.g., a needle). While sustained advances in ultrasound technology have led to greatly enhanced visualization of the anatomy and the needle with high image quality, hand-eye coordination of the practitioner continues to be a challenge. In order to properly position the interventional device, the practitioner must alternate their attention between observing the patient, advancing the needle, and viewing the ultrasound image on a separate screen. Our long-term goal is to develop an advanced visualization platform for ultrasound-guided procedures to overcome this challenge by greatly simplifying hand-eye coordination. The proposed platform will be developed using the latest advances in the augmented reality (AR) technology. Through wearable, see-through AR glasses, the platform will create a virtual display placed in the practitioner's field of view to show live ultrasound images, registered with the transducer and the patient, in the form of a hologram. We hypothesize that such visualization will reduce the time of procedure by 20%. Two specific aims of the project are to: (1) develop augmented reality visualization of live ultrasound images, and (2) characterize technical performance and demonstrate improved efficiency through user studies. This project is aimed at providing the practitioner a more intuitive and efficient platform to perform ultrasound-guided procedures. As these procedures continue to grow, the work is both timely and essential. Further, the project is innovative because we use AR in a novel way to create a single unified display. Our multidisciplinary team with a strong track record of pioneering novel image guidance and AR applications is uniquely qualified for this project. When fully developed, the proposed visualization platform could make ultrasound-guided procedures safer and more precise and accelerate their growth by reducing their complexity.

总结 微创超声引导手术是现代医学的支柱， 这样的程序继续增长。安全、高效和精确地执行这些程序需要 目标解剖结构和介入设备的清晰可视化（例如，针）。虽然持续 超声技术的进步已经大大增强了解剖结构的可视化， 对于具有高图像质量的针，医生的手眼协调仍然是一个挑战。 为了正确地定位介入装置，从业者必须交替他们的注意力， 在观察患者、推进针和在单独的屏幕上查看超声图像之间 屏幕我们的长期目标是开发一个先进的可视化平台，用于超声引导 通过大大简化手眼协调来克服这一挑战。拟议 该平台将使用增强现实（AR）技术的最新进展进行开发。通过 可穿戴，透视AR眼镜，该平台将创建一个虚拟显示器放置在从业者的 视场，以显示与换能器和患者配准的实时超声图像， 一个全息图。我们假设这种可视化将减少20%的手术时间。两 该项目的具体目标是：（1）开发实时超声图像的增强现实可视化， 以及（2）通过用户研究表征技术性能并证明效率的提高。 这个项目旨在为从业者提供一个更直观和有效的平台来执行 超声波引导手术随着这些程序的不断发展，这项工作既及时， 具有本质意义此外，该项目是创新的，因为我们以一种新颖的方式使用AR来创建一个统一的 显示.我们的多学科团队拥有开创性的新颖图像引导和 AR应用程序是唯一有资格为这个项目。当完全开发时，拟议的可视化 该平台可以使超声引导程序更安全，更精确，并加速其发展 通过降低它们的复杂性。
