Claim 0:
1. A method for optical coherence tomography angiography (OCTA) imaging, comprising:
obtaining three or more optical coherence tomography (OCT) B-scans at each of a plurality of cross-sectional positions along a slow axis using a stepped scanning pattern on the slow axis, wherein the obtaining the OCT B-scans includes:
obtaining a first OCT B-scan, a second OCT B-scan, and a third OCT B-scan at a first cross-sectional position of the cross-sectional positions, wherein a first time period between the first and second OCT B-scans is different than a second time period between the second and third OCT B-scans, and wherein a third time period between the first and third OCT B-scans is different than the first and second time periods; and
obtaining, via the stepped scanning pattern on the slow axis, at least one of the OCT B-scans at one or more other cross-sectional positions of the plurality of cross-sectional positions in between the first and second OCT B-scans or second and third OCT B-scans at the first cross-sectional position;

generating multiple OCTA images based on the three or more OCT B-scans at each of the plurality of cross-sectional positions; and
combining the multiple OCTA images to obtain a high dynamic range (HDR) OCTA image.
