项目摘要

DESCRIPTION (provided by applicant): The overall objective of the proposed research is to fully develop and conduct clinical translation of a novel technology that provides minimally invasive surgeons an ability to visualize exposed organ surfaces as well as structures hidden by them, together with a true appreciation of depth. A long-standing need in minimally invasive laparoscopic surgery has been to see inside and around a structure before dissecting, a need that currently used laparoscopes, even when high- definition and stereoscopic, cannot meet. We plan to achieve our objective by integrating 2 real- time surgical imaging modalities: (1) newly emerged 3-dimensional (3D) laparoscopic camera technology that allows visualizing the surgical anatomy with the highest image quality currently available and perception of true depth, and (2) laparoscopic ultrasound capable of visualizing hidden structures. We call the resulting visualization capability stereoscopic augmented reality (AR), in which 3D laparoscopic video (the reality) is augmented with ultrasound findings, especially the blood vessels. Children's National Medical Center and IGI Technologies will combine their complementary expertise to meet the goals of this project. Children's National, the site of the original research and development, brings unparalleled clinical image-guided surgery expertise and resources to facilitate clinical translation. IGI Technologies, a medical imaging small business, focuses on converting academic research into products. Overall, the specific aims of the proposed research are to: (1) create a compact, high-performance, operating room-ready 3D AR visualization system, and (2) test, demonstrate, and characterize the 3D AR visualization system. These aims are designed to develop a clinically viable system and test 2 milestones relating to acceptable image overlay accuracy and system responsiveness. Meeting these milestones will signal successful completion of Phase I and our readiness to transition to Phase II, which will include animal and human testing of the developed system. The proposed system is novel in that no clinical system that combines 3D laparoscopic video and ultrasound exits. Successful execution of the proposed research will create a smart surgical visualization system that promises to provide surgeons greater confidence, minimize complications, shorten procedure times, reduce blood loss, and help expand the utilization of minimally invasive surgeries to beyond their 9%-12% current share of all surgeries. The anticipated benefits will apply equally to pediatric and adult surgery.

描述（由申请人提供）：拟议的研究的总体目标是充分开发和进行一种新型技术的临床翻译，该技术提供了微创外科医生可视化裸露的器官表面以及隐藏的结构的能力，并真正欣赏深度。在剖析之前，在剖析之前和周围的最低侵入性腹腔镜手术的长期需求是，即使在高清晰度和立体镜面也无法满足时，目前使用腹腔镜的需求也是如此。我们计划通过整合2种实时手术成像方式来实现我们的目标：（1）新出现的3维（3D）腹腔镜摄像机技术，允许将手术解剖结构可视化，并具有当前可用的最高图像质量和对真实深度的最高图像质量，以及（2）腹腔镜超声可视化可视化的隐藏式隐藏结构。我们称之为由此产生的可视化能力立体化功能增强现实（AR），其中3D腹腔镜视频（现实）具有超声检查结果，尤其是血管。儿童国家医疗中心和IGI技术将结合其补充专业知识，以实现该项目的目标。原始研究与开发的儿童国家（儿童国家）带来了无与伦比的临床图像引导的手术专业知识和资源，以促进临床翻译。 IGI Technologies是一家医学成像小型企业，致力于将学术研究转化为产品。总体而言，拟议的研究的具体目的是：（1）创建一个紧凑的，高性能的3D AR可视化系统，以及（2）测试，演示和表征3D AR可视化系统。这些目标旨在开发一个临床上可行的系统和测试与可接受的图像叠加精度和系统响应性有关的2个里程碑。达到这些里程碑将表示成功完成第一阶段以及我们准备过渡到第二阶段，其中包括对开发系统的动物和人类测试。提出的系统是新颖的，因为没有结合3D腹腔镜视频和超声出口的临床系统。拟议研究的成功执行将创建一个智能的外科可视化系统，该系统有望为外科医生提供更大的信心，最大程度地减少并发症，缩短手术时间，减少失血并有助于将最小侵入性手术的利用扩大到所有手术中当前份额的9％-12％以上。预期的益处将同样适用于儿科和成人手术。
