ENHANCED OPTICAL ANGIOGRAPHY USING INTENSITY CONTRAST AND PHASE CONTRAST IMAGING METHODS

摘要

The methods described herein are methods to ascertain motion contrast within optical coherence tomography data based upon intensity. The methods of the invention use logarithm operation to convert the multiplicative amplitude or intensity fluctuations (speckle) into the additive variations and recovers the motion contrasts by removing the speckle free signals (static regions) through statistical analysis.
