Eye doctors use lenses to look inside the back of the eye, at the retina, to search for diseasescausing vision problems. With these lenses, they can only see the surface of the retina. Also,what they see is rarely recorded. Eye-witness testimony of the eye doctor is how clinicaldiagnosis is done at this time. A new technology called OCT can show pictures of the retinabelow the surface. These pictures are recorded first and then analyzed by the eye doctor.Since these devices only see a small area of the retina at a time, eye doctors prefer the oldway of looking through the retina directly using lenses.We propose to develop a new OCT scanner that can record a picture of the full retina, thesame or better than the area seen with lenses directly, so doctors dont miss anything. At thesame time, OCT pictures show what's below the surface, like blood vessels. Since the retinapictures are recorded, these can be interpreted and discussed by more than one doctor, andevent sent to another clinic for more analysis and expert opinion.We propose to develop computer programs that use equations to make measurements fromthese pictures. So not only can the doctor see below the retina over a wide area, they canalso get measurements that let them decide if a region inside the retina is healthy or if there issome problem such as damaged cells in the retina, poor or damaged blood supply, or anyother damage.The OCTSurfer technology that we propose has the potential to make it easy for doctors tofind diseases by making detailed and minute measurements that are difficult to make visually.This will lower the chances of errors, like when something is judged to be a problem when itisnt, or when a problem is missed. People living far from cities can benefit by sending theirimages to a eye doctor in a city clinic. Optometrists could use OCTSurfer to screen fordisease and refer people to eye specialists for proper diagnosis.

眼科医生使用镜片观察眼睛后部的视网膜，以寻找引起视力问题的疾病。使用这些镜片，他们只能看到视网膜的表面。而且，他们所看到的很少被记录下来。眼科医生的目击者证词就是此时临床诊断的方式。一种称为 OCT 的新技术可以显示表面以下视网膜的图片。这些图片首先被记录下来，然后由眼科医生进行分析。由于这些设备一次只能看到视网膜的一小部分区域，眼科医生更喜欢使用镜头直接通过视网膜进行观察的旧方法。我们建议开发一种新的 OCT 扫描仪它可以记录完整视网膜的图片，与直接通过镜片看到的区域相同或更好，因此医生不会错过任何东西。同时，OCT 图片显示表面以下的物质，例如血管。由于视网膜图像被记录下来，这些图像可以由多个医生进行解释和讨论，并将事件发送到另一家诊所以进行更多分析和专家意见。我们建议开发计算机程序，使用方程式从这些图像中进行测量。因此，医生不仅可以看到视网膜下方的大范围区域，还可以通过测量来确定视网膜内的某个区域是否健康，或者是否存在一些问题，例如视网膜细胞受损、血液供应不良或受损，或任何其他损害。我们提出的 OCTSurfer 技术有潜力使医生通过进行肉眼难以进行的详细而细致的测量来轻松发现疾病。这将降低出错的机会，例如当某物被判断为问题时不是这样，或者是当问题被遗漏时。居住在远离城市的人们可以通过将图像发送给城市诊所的眼科医生来受益。验光师可以使用 OCTSurfer 来筛查疾病，并将人们转介给眼科专家进行正确的诊断。
