DESCRIPTION (provided by applicant): Endoscopic visualization is of primary importance for minimally invasive surgery (MIS) procedures and various clinical diagnoses. However, a known limitation of current endoscopic imaging technology for some procedures and applications is the limited field of view. For better comprehension of the operating field, it is highly desirable and in some procedures critically important, to be able to view panoramically. Under previous NIH support, InterScience, Inc. has developed a "C-View" endoscope system which is able to capture a field of view larger than a hemisphere (3@ steradian solid angle) onto a single 2D image plane. However, because this endoscopic system delivers a very wide 3D field of view to a single 2D image plane, objects in the panoramic field of view suffer from the inherent barrel distortion when displayed on a traditional 2D display. The objective of this SBIR effort is to develop compatible display technologies that can present the panoramic image collected by such an endoscope to the clinician. Under the Phase I effort, two approaches have been pursued to achieve this. One is to optically recreate compatible panoramic images on a more than hemispherical 3D screen by the projection based on an innovative optical system. The second approach is to display a small portion of the panoramic image in a head-mounted 2D display, and the different portion with different angle of view can be displayed by tracking the head motion. With a combination of a wide-field-of-view endoscope and the proposed immersive display system, it will allow clinicians to situate in an immersive virtual reality environment as exactly what the endoscope locates. Clinical diagnoses and MIS will greatly benefit from such an endoscopic imaging and displaying system. During the Phase I effort, we have successfully developed the concepts and designs, and demonstrated a preliminary bench top projection system. This Phase II effort will focus on the advanced developments, implementations and tests of the two proposed immersive display technologies for clinical applications. The specific Phase II emphasis is to optimize the optical designs, develop compatible software, fabricate the two different prototypes with software integrated, as well as conduct corresponding experimental tests and evaluations in collaboration with medical clinicians PUBLIC HEALTH RELEVANCE: The proposed enhanced endoscopic display technology will provide enhanced visualization and immersive display opportunities for all applications of minimally invasive surgery (MIS) including robotic surgery applications. The development effort is concentrated on a standard display and a head mounted display configuration.

描述(由申请者提供)：内窥镜可视化对于微创手术程序和各种临床诊断非常重要。然而，目前的内窥镜成像技术对于某些程序和应用的一个已知限制是有限的视野。为了更好地理解操作领域，能够全景查看是非常可取的，而且在某些过程中非常重要。在NIH以前的支持下，InterScience，Inc.开发了一种“C-view”内窥镜系统，该系统能够在单个2D图像平面上捕获比半球(3@立体立体角)更大的视野。然而，由于该内窥镜系统将非常宽的3D视场传递到单个2D图像平面，所以当在传统2D显示器上显示时，全景视场中的对象遭受固有的桶形失真。这项SBIR工作的目标是开发兼容的显示技术，将由这种内窥镜收集的全景图像呈现给临床医生。在第一阶段的努力下，采取了两种办法来实现这一目标。一种是通过基于创新光学系统的投影，在超过半球的3D屏幕上光学重建兼容的全景图像。第二种方法是在头盔2D显示器上显示全景图像的一小部分，通过跟踪头部运动可以显示不同视角的不同部分。通过宽视场内窥镜和拟议的沉浸式显示系统的组合，它将允许临床医生处于沉浸式虚拟现实环境中，就像内窥镜所处的位置一样。这种内窥镜成像和显示系统将极大地帮助临床诊断和管理信息系统。在第一阶段的工作中，我们成功地开发了概念和设计，并演示了初步的台式投影系统。这项第二阶段的工作将集中在两项拟议的临床应用沉浸式显示技术的高级开发、实施和测试上。第二阶段的重点是优化光学设计，开发兼容的软件，集成软件制造两种不同的原型，并与医疗临床医生合作进行相应的实验测试和评估，以提高与公共卫生的相关性：拟议的增强型内窥镜显示技术将为包括机器人手术应用在内的所有微创手术(MIS)应用提供增强的可视化和沉浸式显示机会。开发工作集中在标准显示器和头盔显示器配置上。
