We have studied experimentally and theoretically spatial distributions of factors describing sensitivity of the statistical moments of distributions of times of flight (DTOFs) of photons penetrating through the medium to changes in absorption coefficient. Additionally, the moments subtraction procedure, based on difference between statistical moments measured at two interoptode distances was applied in order to modify the sensitivity profiles.
