Abstract
Retinal layer segmentation in optical coherence tomography (OCT) data is improved by using OCT angiography (OCTA) data to enhance a target retinal layer within the OCT data that may lack sufficient definition for segmentation. The OCT data is enhanced based on a mixture of the OCT data and OCTA data, such that contrast in the OCT data is enhanced in areas where OCT and OCTA data are dissimilar, and is reduced in areas where the OCT and OCTA data are similar. The target retinal layer in the OCT data is segmented based on the enhanced data. Two en face images of the OCTA data that include the target retinal layer are used to check for errors in the segmentation of the target retinal layer in the OCT data. Identified errors are replaced with an approximation based on the locations of top and bottom retinal layers of one of the en face images.
