Claim 9:
10. A method comprising:
obtaining, via an optical coherence tomography (OCT) system, an OCT dataset associated with a sample, the OCT dataset including complex values;
determining multiple sets of variance values between A-scans of the OCT dataset, wherein individual sets of the multiple sets include variance values determined at different phases spaced relative to a base phase, and wherein the base phase is different for each individual set of the multiple sets;
determining a bulk motion phase shift for each individual set of variance values;
averaging the determined bulk motion phase shifts for the multiple sets to determine a bulk motion phase compensation;
compensating the OCT dataset based on the bulk motion phase compensation; and
generating a flow image of the sample based on the compensated OCT dataset.
