1. A method of analyzing optical coherence tomography data, said method comprising: acquiring a data set using an optical coherence tomography (OCT) system, said data set comprising a plurality of measurements of a sample, wherein the data set contains at least two measurements that were made at approximately the same location on the sample; processing the OCT data set to generate complex OCT signals, wherein the complex signal can be described by an intensity and a phase; generating motion contrast information by taking the difference between at least two complex OCT signal values corresponding to OCT measurements acquired at approximately the same location on the sample, wherein the difference includes both phase and intensity information; and storing or displaying the resulting motion contrast information.
