The present disclosure describes system and method, include small recessed (OCT) image of optical coherence tomography for selecting. The system and method for description receive a variety of oct images. Oct image sections select for further processing, and middle line is tracked boundary and generated in retina and non-retinal tissue. Line difference generates. Then candidates oct image responses are generated in generated temperature difference line. Minimum point is identified in the oct images that each poor line generates, the minimum points of oct images to these recesses correspond to and be identified as including oct images.
