Abstract :
In a simulation study the description of an object is very important for high speed calculation in photon transportation with a Monte Carlo method. For this object description we developed a maximum rectangular region (MRR) method in 2000 (TNS vol.47, No.3) thereby reducing the calculation time. In this paper we proposed a more efficient method in which we considered the location of a photon within a rectangular region. This method could reduce the calculation time as compared with the MRR method.
