Flow diagram of the PT-CLEAN algorithm to remove phase accumulation and shadowing. A point spread function is created using the analytical model. The first pixel in depth with a PT-OCT signal above threshold is then selected to calculate the deconvolution kernel. Two new images are created; a B-scan from which the deconvolution kernel was subtracted and a new image where the selected pixel is recorded. The final image is reconstructed by convoluting each of the individual saved pixels to a 1-D Gaussian along the depth dimension.
