The broader impact/commercial potential of this I-Corps project is based on significant improvements in accuracy and cost reduction of eye-related disease diagnosis by providing a high-quality, high-speed tissue imaging solution. Specifically, the project will shorten clinical scan time, and as a result, increase image resolution while reducing the number of required patient clinic visits. These improvements directly lower associated medical costs. The project goal is to create a new-generation of Optical Coherence Tomography (OCT), a technique that is used in the clinical practice to provide cross-sectional images of the retina. Currently, the biggest challenge faced by OCT clinical applications is their slow scan speed, which leads to low image resolutions and therefore unsatisfying clinical experience. A high-quality, high-speed signal processing tool is needed for reliable clinical decision-making and disease monitoring with OCT systems.This I-Corps project will further develop a new-generation of Optical Coherence Tomography (OCT). The I-Corps project will explore the commercial potential of the innovation, a system capable of decreasing the signal processing time of swept source OCT (SS-OCT) devices by up to ten times according to lab tests. This device is based on a family of novel signal processing algorithms that significantly improve the accuracy and speed required for the medical images to be acquired. The SS-OCT platform will be enhanced in terms of the image acquisition speed, accuracy, and cost. This, in turn, will decrease the number of visits a patient needs to make to an ophthalmology clinic while increasing the overall clinic capacity to attend visiting patients per day, generating more revenue for those centers.

该 I-Corps 项目的更广泛影响/商业潜力基于通过提供高质量、高速组织成像解决方案，显着提高了眼部相关疾病诊断的准确性并降低了成本。具体来说，该项目将缩短临床扫描时间，从而提高图像分辨率，同时减少患者就诊所需的次数。这些改进直接降低了相关的医疗成本。该项目的目标是创建新一代光学相干断层扫描（OCT），这是一种在临床实践中用于提供视网膜横截面图像的技术。 目前OCT临床应用面临的最大挑战是扫描速度慢，导致图像分辨率低，临床体验不理想。使用 OCT 系统进行可靠的临床决策和疾病监测需要高质量、高速的信号处理工具。该 I-Corps 项目将进一步开发新一代光学相干断层扫描 (OCT)。 I-Corps 项目将探索该创新的商业潜力，根据实验室测试，该系统能够将扫频源 OCT (SS-OCT) 设备的信号处理时间减少多达十倍。该设备基于一系列新颖的信号处理算法，可显着提高采集医学图像所需的准确性和速度。 SS-OCT平台将在图像采集速度、精度和成本方面得到增强。反过来，这将减少患者需要到眼科诊所就诊的次数，同时增加诊所每天接待患者的整体能力，从而为这些中心创造更多收入。
