    OCT Shines with a New Type of Contrast

    A diagnostic workhorse, optical coherence tomography (OCT), provides high-resolution 3D imaging of subsurface tissue structures. Most likely, for your last eye exam, the ophthalmologist took cross-sectional pictures of your dilated eyes to measure the thickness of your retinal layers using OCT. Minimally invasive microscopic OCT imaging is widely affordable and recognized as a tool of choice. Minted in 1991 by James Fujimoto's group at MIT who first conjoined the elements comprising OCT, the technique has been evolving as a multimodal platform for decades as researchers have developed multiple ways to add functionality to OCT. One of the most promising ...
