DESCRIPTION (provided by applicant): The physical world around us is three-dimensional (3D), yet most existing display systems with flat screens can handle only two-dimensional (2D) flat images that lack the third dimension (depth) information. This fundamental restriction greatly limits the capability of human being in perceiving and understanding the complexity of real world objects. In contrast to conventional medical image visualization that are primarily based on 2D flat screen, the "true 3D display" we proposed herein possesses a physical 3D display volume, and places each 3D "voxel" in the displayed 3D images at the true 3D (x, y, z) spatial position. Each voxel, analogous to a pixel in a 2D image, emits light from that position to form a real 3D image in the eyes of viewers. The true 3D display technology provides both physiological and psychological depth cues to human visual system to perceive 3D objects and is considered as the Holy Grail solution to true 3D visualization of medical image, and many other display problems. Xigen LLC has recently made a technology breakthrough and developed a revolutionary concept of the "hybrid multiview/volumetric (HyMV)" 3D display that is able to provide true 3D displaying capability in both the volumetric display mode and the multiview 3D display mode, simultaneously overlaying on each other, or displayed in separate modes as controlled by uses. The volumetric 3D images provide true 3D measurement of and spatial relationship among the displayed 3D objects, while the multiview 3D images provide photo-quality textured surface properties of the displayed 3D objects. By seamlessly integrating these two 3D display modes into a single 3D display system, the proposed HyMV technology offers an unprecedented true 3D display capability never available before: a volumetric 3D display capable of showing both true 3D positions of voxels, as well as various surface properties (occlusion, shining, reflection, shadow, etc) that are essential to many high image quality medical visualization applications. We propose this SBIR effort to perform thorough investigation of the proposed novel concept, carry out design and tradeoffs, build a functional prototype, and assess its technical efficacy for image-guided radiaotion intervention for cancer treatment.

We plan to build and test a functional prototype, focusing our effort in demonstrating several key capabilities of this breakthrough innovation. We now summarize unique advantages of the proposed HyMV 3D display system: - For the first time, achieve coherent volumetric and multiview 3D display in single system; - Preserve 3D spatial voxels and 3D measurement capability while producing photo-quality 3D images with realistic surface properties (shining, shadow, occlusion, etc); - Offer volumetric mode, multiview mode and simultaneous multiview/volumetric mode in 3D display, suited for various visualization and 3D measurement applications; - High spatial resolution, full color display is easy to implement using the latest DMD devices. - No special viewing glasses or any special eyewear is needed to view the 3D images; - Simple and elegant system structure design. The major innovations of this SBIR effort include: - Novel concept to seamlessly integrate multiview and volumetric displays in single system; - Novel design of hybrid rotating screen, accommodating both display modes; - Compact and portable overall system design; - Novel true 3D user interface device design allowing for interaction with displayed true 3D images; - Integrated true 3D volumetric/multiview display hardware/software tailored for IGRI applications. The follow-on Phase 2 program will afford us to perform clinical study on the interventional efficacy and clinical outcomes of the technology applications. The Phase 3 program will carry out productization and commercialization of the unique true 3D display product. Beyond the image-guided radiotherapy intervention, applications of true 3D display technology are enormous, including various areas of medical imaging (e.g., image guided therapy, clinical diagnosis, procedure training, simulation, pre-treatment planning, and clinical hypothesis validation), military (e.g. air traffic control, pilot training, battlefield visualization, telemedicine) and commercial (e.g., 3D TV, virtual reality, advertizing, computer aided design, scientific computing, video games, stadium displays, etc.) The 3D display will provide a new level of realism and literally add a new dimension to information display tool set we now have.

描述（由申请人提供）：我们周围的物理世界是三维（3D）的，但大多数现有的平面屏幕显示系统只能处理缺乏三维（深度）信息的二维（2D）平面图像。这种根本性的限制极大地限制了人类感知和理解现实世界物体的复杂性的能力。与主要基于 2D 平面屏幕的传统医学图像可视化相比，我们在此提出的“真实 3D 显示”拥有物理 3D 显示体积，并将显示的 3D 图像中的每个 3D“体素”放置在真实 3D（x , y, z) 空间位置。每个体素类似于 2D 图像中的像素，从该位置发出光线，在观看者眼中形成真实的 3D 图像。真3D显示技术为人类视觉系统提供生理和心理深度线索来感知3D物体，被认为是医学图像真3D可视化和许多其他显示问题的圣杯解决方案。 Xigen LLC最近取得了技术突破，开发出“混合多视图/体积（HyMV）”3D显示的革命性概念，能够在体积显示模式和多视图3D显示模式下提供真正的3D显示能力，同时叠加彼此重叠，或根据用户的控制以单独的模式显示。体积 3D 图像提供所显示 3D 对象的真实 3D 测量和空间关系，而多视图 3D 图像提供所显示 3D 对象的照片质量纹理表面属性。通过将这两种 3D 显示模式无缝集成到单个 3D 显示系统中，所提出的 HyMV 技术提供了前所未有的真实 3D 显示功能：体积 3D 显示能够显示体素的真实 3D 位置以及各种表面属性（遮挡、发光、反射、阴影等）对于许多高图像质量医学可视化应用至关重要。我们提出这项 SBIR 工作，对所提出的新概念进行彻底调查，进行设计和权衡，构建功能原型，并评估其用于癌症治疗的图像引导放射干预的技术功效。 XIGEN LLC 的专有信息。 0 NIH SBIR PA 07-042 公共卫生相关性：第一阶段 SBIR 工作的主要目标是证明具有前所未有的混合体积/Multiplan 3D 显示功能的新型体积 3D 显示概念的可行性。我们计划构建并测试一个功能原型，重点展示这一突破性创新的几个关键功能。现在，我们总结了所提出的 HyMV 3D 显示系统的独特优势： - 首次在单个系统中实现相干体积和多视图 3D 显示； - 保留 3D 空间体素和 3D 测量能力，同时生成具有真实表面属性（发光、阴影、遮挡等）的照片质量 3D 图像； - 在3D显示中提供体积模式、多视图模式和同时多视图/体积模式，适合各种可视化和3D测量应用； - 使用最新的 DMD 设备可以轻松实现高空间分辨率、全彩显示。 - 无需特殊观看眼镜或任何特殊眼镜即可观看 3D 图像； - 简洁优雅的系统结构设计。 SBIR 工作的主要创新包括： - 将多视图和体积显示无缝集成到单个系统中的新颖概念； - 新颖的混合旋转屏设计，兼容两种显示模式； - 整体系统设计紧凑、便携； - 新颖的真 3D 用户界面设备设计，允许与显示的真 3D 图像进行交互； - 专为 IGRI 应用量身定制的集成式真实 3D 体积/多视图显示硬件/软件。后续的二期计划将使我们能够对技术应用的介入疗效和临床结果进行临床研究。第三阶段计划将进行独特的真3D显示产品的产品化和商业化。除了图像引导放射治疗干预之外，真正的 3D 显示技术的应用非常广泛，包括医学成像的各个领域（例如图像引导治疗、临床诊断、手术培训、模拟、治疗前计划和临床假设验证）、军事（例如空中交通管制、飞行员培训、战场可视化、远程医疗）和商业（例如 3D 电视、虚拟现实、广告、计算机辅助设计、科学计算、视频游戏、体育场显示等）显示将提供新的真实感水平，并为我们现在拥有的信息显示工具集增加一个新的维度。 XIGEN LLC 的专有信息。 1 NIH SBIR PA 07-042
