Abstract

We propose a B-scan-wise- multi-focus average method (B-MFA) to suppress multiple scattering noise for in-vivo imaging. This method uses only multiple B-scans with modulated focus position for complex averaging, and a one-dimensional computational refocusing is applied to cancel the defocus in each B-scan. To validate the proposed method, ten medaka fish were measured in-vivo without anesthesia. The results show that B-MFA can enhance the OCT image contrast in the deep regions.
