Abstract
In this work, we demonstrated that bulk motion could lead to increased background in OCT microangiography image. Based on our motion analysis, we developed an adaptive thresholding method to reduce artifact in OCT microangiography caused by transient bulk motion. Motion artifact reduced microangiography was demonstrated in a 1.3μm spectral domain OCT system using graphic processing unit (GPU) for real-time signal processing. We conducted in vivo microvasculature imaging on human skin. Our results clearly show that the adaptive thresholding is highly effective in motion artifact removal.
