Bias Field Correction for Retinal Perfusion Heterogeneity Analysis of Optical Coherence Tomography Angiography

Date created
In this thesis, a method for bias field correction is proposed for Optical Coherence Tomography Angiography (OCT-A) images. The bias field artifact is an intensity nonuniformity present on OCT-A images caused by inaccuracies during image acquisition. The OCT volumetric data is used to estimate bias produced due to the tilt of the retina. Bias field correction will occur prior to a 2-D registration algorithm used to correct for micro-saccadic motion and construct a clear, high-quality image of the retina for retinal perfusion heterogeneity analysis.
