Abstract:
A method for coherence noise filtering in an optical coherence tomography system comprises generating a background image containing coherence noise, generating a sample image, generating composite pixel values from pixel values in the background image based on the mean pixel values from lines in the background image, and subtracting the composite pixel values from complex pixel values in the sample image.
