Abstract:
1. A method of providing a digital code associated with a three dimensional optical coherence tomography image, the method comprising: collecting the three dimensional optical coherence tomography image of a subject; extracting a two dimensional projection image from an internal region of the three dimensional optical coherence tomography image, wherein the internal region is a slice of partial and non-vanishing thickness contoured to a layer of interest within the three dimensional optical coherence tomography image, wherein the two dimensional projection image is created by processing an image intensity along a depth axis of the three dimensional optical coherence tomography image to determine the layer of interest; and reducing the two dimensional projection image to a first code that is unique to the three dimensional optical coherence tomography image based on the extracted two dimensional projection image, wherein reducing further comprises reducing the two dimensional projection image to the first unique code based on a defined set of structural or functional information contained within the image.
