In the field of medical X rays image, it is important how to seize a quantity of being affected by radioactivity to the human body. Then, in the case when dropping affection by radioactivity dose, quantum noise increases on inevitability, and some counter-measure methods become central problem. In this paper, a new trial of wide-sense digital filter for estimating adaptively the non-Gaussian stochastic systems will be proposed in the hierarchical form based on the orthogonal series expanded Bayes' theorem. Then, the effectiveness of proposed recursive algorithm will be experimentally confirmed through several applications to real medical X-ray images.
