In this paper we will propose a deterministic approach to model the radio propagation channels complex indoor environments. This technique applies the SBR method to find equivalent sources (images) in each launched ray tube, and sums the receiving amplitude contributed by all images coherently. We verify our SBR/image approach by comparing the numerical results in two canonical examples where closed-form solutions exist. The good agreement indicates that our method can provide a good approximation of high frequency radio propagation inside corridors where reflection is dominant. In the special case of a curved corridor, which can not be solved by analytic methods, we find a "focusing" effect that at some certain point the receiver will receive high power, even though it is out of sight. This SBR/image method can be enhanced by including the wall penetration and wedge diffraction effects, and even more complicated indoor environments will be tackles in the near future.
