Abstract Colon cancer is a leading cause of cancer death in the United States and worldwide. Colonoscopy is the preferred screening method at an estimated annual cost of about $24 billion in the US. Unfortunately, many lesions are missed because they can remain hidden from view behind folds and flexures of the colon. Current methods of increasing the field of view are ineffective and some are very expensive, preventing the adoption of these methods into clinical practice. In this proposal, we propose to develop a single viewpoint panoramic imaging technology which can provide 360-degree side-view of the colon. The proposed panoramic imaging system consists of an array of imaging systems which share the same viewpoint, addressing the key barrier in reconstructing the panoramic image from multiple imaging systems. We will develop a unique monolithic opto-mechanical design to integrate all subsystems precisely without active alignment. The proposed single viewpoint panoramic imaging system can be either integrated to the new colonoscope so that the colonoscope will have standard forward view and 360- degree panoramic side-view, or built as a snap-on attachment for the current commercial colonoscopes to provide 360-degree panoramic side-view. To demonstrate the imaging capability of the proposed single viewpoint panoramic system, we will first develop and characterize a single viewpoint panoramic attachment for the standard colonoscope, and then evaluate the performance in detecting polyps and compare to a standard colonoscope. The proposed single viewpoint panoramic imaging system will maximize the detection of polyps and substantially reduce the incidence of colon cancer. It will benefit the patients and society in five-fold: reducing incidence of colon cancer, reducing the chance of ‘interval’ cancer, decreasing overall morbidity and mortality, increasing the interval between colonoscopies, and reducing the economic burden of this disease.

抽象的 结肠癌是美国和全世界癌症死亡的主要原因。结肠镜检查是 首选的筛查方法，在美国估计每年花费约 240 亿美元。不幸的是，许多 病变会被遗漏，因为它们可能隐藏在结肠的褶皱和弯曲后面而看不见。当前的 增加视野的方法效果不佳，而且有些方法非常昂贵，阻碍了采用 将这些方法应用到临床实践中。 在本提案中，我们建议开发一种单视点全景成像技术，该技术可以提供 结肠 360 度侧视图。所提出的全景成像系统由成像阵列组成 共享相同视点的系统，解决了重建全景图像的关键障碍 多个成像系统。我们将开发一种独特的单片光机械设计来集成所有 无需主动对准即可精确地调整子系统。所提出的单视点全景成像系统可以 可以集成到新的结肠镜中，以便结肠镜具有标准的前视图和 360 度视角 度全景侧视图，或作为当前商用结肠镜的卡扣式附件构建 提供360度全景侧视图。 为了展示所提出的单视点全景系统的成像能力，我们将首先开发 并表征标准结肠镜的单视点全景附件，然后评估 检测息肉的性能并与标准结肠镜进行比较。 所提出的单视点全景成像系统将最大限度地检测息肉，并基本上 降低结肠癌的发病率。它将给患者和社会带来五方面的好处：减少疾病的发生率 结肠癌，减少“间期”癌症的机会，降低总体发病率和死亡率，增加 结肠镜检查之间的间隔时间，并减少这种疾病的经济负担。
