Indeed, I second that the time is now. There are several imaging modalities/organs that provide diagnostic information about a variety of human functions or diseases. For example, retina is a unique organ that is amenable to imaging of central nervous system, cardio-vascular system, and microvasculature without any incision. This allows us to detect, screen, monitor, and predict risk for diseases such as diabetic retinopathy, macular degeneration, glaucoma, and even cardio-vascular risk, Alzheimer's, and stroke.

If this interests you and you have developed the expertise, there is another startup opportunity to explore -- please email me at [email protected]. We are bunch of machine learning PhDs, developing/publishing and commercializing deep learning algorithms for disease/risk identification from retinal photography. We play with millions of retinal images, and it's a lot of fun!
