These isolated point measurements deserve pertain roles in the OCT reconstruction.The ART3 algorithm is a robust method dealing with practically noisy or even partly missing projections,and is friendly to integrate the information from various sources.Most of the suggestions on fusing information inevitably introduce high frequencies,which never exist in the field,into the interation.And these high frequencies over-suppress the expected low frequency components and cause the reconstraction non-stable.An adaptive way is developed to take a good use of pointwise priori.By analyzing the simulated experiments,some deserved attention to the application of priori in OCT is strongly suggested.
