METHOD FOR ANALYZING AVASCULAR REGIONS IN OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGES

摘要

Eye-related pathologies are diagnosed, or monitored, by useof optical coherence tomography angiography (OCTA) images. Avascular regions in the OCTA image are identified and optionally labeled as test or nonessential for particular applications. Nonessential avascular regions may correspond to avascular regions similar to those typicallyfound in healthy eyes or to low quality regions of the OCTAimage. Nonessential avascular regions may be removed, and the remaining avascular regions may be designated test avascular regions and submitted for analysis, e.g., by calculating anavascular index of the test avascular regions or by comparing the test avascular regions to a database of healthy and/or diseased avascular regions, or by usinga neural network trained on the database.
