In this paper, a new inverse analysis method were introduced for optical computed tomography (optical C.T.). In optical C.T., near-inferred light is exposed into human body and scattered light is measured to detect a oxygenated part. This inverse problem is reduced to estimate the absorption distribution from scattered light on a surface of human body. To relax the ill-posed of this inverse problem, we proposed this problem is reduced to 0-1 integer problem by considering absoption coefficient as two discrete values of tumor and normal tissue. And severe constraint on discrete value is relaxed by treating absorption coefficient as probability variable. Simple 3D example problem was solved to demostrate the usefulness of this method.
