1. A method of collecting optical coherence tomography (OCT) image data of an eye of a patient, said method comprising: collecting two or more OCT scans, wherein each scan is made over a series of transverse location on the eye of a patient; averaging the two or more scans to create an averaged scan; determining a quality metric for the averaged scan; comparing the quality metric to a predefined value to determine whether additional OCT scans should be collected; and collecting one or more additional scans, adding the additional scans to the average and determining a quality metric until the determined quality metric exceeds a predefined value.
