    Statistics of Optical Coherence Tomography Data From Human Retina
    Optical coherence tomography (OCT) has recently become one of the primary methods for non-invasive probing of the human retina. The pseudo-image formed by OCT (the socalled B-scan) varies probabilistically across pixels due to complexities in the measurement technique. Hence, sensitive automatic procedures of diagnosis using OCT may exploit statistical analysis of the spatial distribution of reflectance. In this paper, we perform a statistical study of retinal OCT data. We find that the stretched-exponential probability density function can model well the distribution of intensities in OCT pseudo-images. Moreover, we show a small, but significant correlation between neighbor pixels when measuring OCT ...
