Abstract

In this study, we propose a B-scan-wise-multi-focus averaging method (B-MFA) to suppress the multiple scattering noise in optical coherence tomography. This method uses multiple B-scans with different focus positions. These B-scans were one-dimensionally computationally refocused and complex averaged. To verify the multiple scattering noise suppression ability of this method, we measured a phantom consisting of scattering and non-scattering layers. The results show that BMFA suppresses multiple scattering noise.
