| Abstract: | n the diffuse reflectance reemitted from the biological tissuewith reflectance spectrophotometry(RS) can decide the photosensitizer concentration in tissue.In this paper,the absolute sensitivity of the method is given by the random--walk model of photon migration.Comparing with the results of the diffusion theory, we show that themodel of the photon migration is applicable to the measurmen of the photosensitizer concentration. |

| Keywords: | photosensitizer concentration sensitivity t the model of photon migration diffusion theory |
