1. A method of processing optical coherence tomography (OCT) data obtained from a sample, the method comprising: analyzing at least a first subset of an OCT data set to identify landmark region data; placing the OCT data set in correspondence with the landmark region data; and processing at least a second subset of the OCT data set based on the correspondence of the OCT data set to the landmark region data, the OCT data set being derived from measurements of backscattering or back-reflection as a function of optical depth within the sample.
