Abstract

Quantitative analysis of OCT data can be strongly hampered by speckle. We propose a new method to reduce speckle, operating on a single Fourier-domain optical coherence tomography (FD-OCT) A-line. The full acquired spectrum is used for image generation, exhibiting fully developed speckle. By subdividing the same acquired spectrum in a number of distinct narrower windows, each with a different center frequency, several independent speckles can be generated. These can be averaged to yield a lower-resolution image with strongly reduced speckle. The full resolution image remains available for human interpretation; the low resolution version can be used for parametric imaging. We demonstrate this technique using in vivo intravascular optical frequency domain imaging (OFDI) data.
