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），但是大多数带有平面屏幕的显示系统只能处理缺乏第三维（深度）信息的二维（2D）平面图像。这种基本限制极大地限制了人类在感知和理解现实世界对象的复杂性方面的能力。与主要基于2D平面屏幕的常规医学图像可视化相反，我们在本文提出的“真3D显示”具有物理3D显示卷，并将每个3D“ Voxel”放在显示的3D图像中，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，以在观众眼中形成真实的3D图像。真正的3D展示技术为人类视觉系统提供了生理和心理深度线索，以感知3D对象，并被视为神圣的圣杯解决方案，用于对医学图像的真实3D可视化以及许多其他显示问题。 Xigen LLC最近取得了技术的突破，并开发了“混合多视图/体积（HYMV）” 3D显示屏的革命性概念，该显示能够在体积显示模式和Multiview 3D显示模式下提供真正的3D显示功能，同时叠加层次彼此，或以用途控制的单独模式显示。体积3D图像提供了显示的3D对象之间的真实3D测量和空间关系，而Multiview 3D图像则提供了显示的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一个3D显示系统中，提出的HYMV技术提供了前所未有的True 3D显示功能，以前从未有过：一个能够显示Voxels的真正3D位置的体积3D显示屏，以及各种表面属性（遮挡，闪亮，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。我们提出了SBIR的努力，以对拟议的新颖概念进行彻底研究，进行设计和权衡，建立功能性原型，并评估其对癌症治疗的图像引导的辐射干预措施的技术功效。 Xigen LLC的专有信息。 0 NIH SBIR PA 07-042公共卫生相关性：I阶段I SBIR工作的主要目标是证明具有前所未有的混合体积/乘数/乘数3D显示屏的新型体积3D显示概念的可行性。我们计划构建和测试功能性原型，集中精力展示这项突破性创新的几个关键能力。现在，我们总结了提议的HYMV 3D显示系统的独特优势： - 首次在单个系统中实现连贯的体积和多视图3D显示； - 保留3D空间体素和3D测量能力，同时产生具有逼真的表面特性（闪亮，阴影，遮挡等）的照片质量的3D图像； - 在3D显示中提供体积模式，多视图模式和同时的多视图/体积模式，适用于各种可视化和3D测量应用程序； - 高空间分辨率，使用最新的DMD设备易于实现全颜色显示。 - 不需要特殊的观看眼镜或任何特殊的眼镜来查看3D图像； - 简单而优雅的系统结构设计。这项SBIR工作的主要创新包括： - 在单个系统中无缝整合多视图和体积显示器的新颖概念； - 混合旋转屏幕的新型设计，可容纳两种显示模式； - 紧凑和便携式整体系统设计； - 新颖的True 3D用户界面设备设计允许与显示的真3D图像进行交互； - 集成的TRUE 3D体积/多览显示为IGRI应用程序量身定制的硬件/软件。后续第二阶段计划将使我们对技术应用的介入功效和临床结果进行临床研究。第三阶段计划将对独特的True 3D显示产品进行生产和商业化。除了图像引导的放射疗法干预外，真正的3D显示技术的应用是巨大的，包括各种医学成像领域（例如，图像指导疗法，临床诊断，程序培训，模拟，治疗预处理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）3D显示现实主义的级别，并从字面上添加了一个新的维度，为我们现在拥有的信息显示工具集。 Xigen LLC的专有信息。 1 NIH SBIR PA 07-042
