The mean mammary gland dose, which is used as an index of the dose of exposure to radiation in mammography, is obtained by multiplying the in-air exposure on the entrance surface by the absorbed dose conversion factor. Sobol et al. reported a method of calculating the absorbed dose conversion factor that is determined by x-ray quality(tube voltage and half-value layer), compressed dreast thickness, and breast composition. A method of calculating mean mammary gland dose, however, has not been established, and no software for estimation of the dose of exposure to radiation in mammography has been developed. Recently, the authors developed software for the estimation of exposure dose that can be easily used in a facility without a dosimeter. They confirmed that the use of this new software enabled the calculation of meanmammary gland dose based on the mammary gland ratio. In a facility without measurement equipment such as a dosimeter, a user can estimate the exposure dose without difficulty simply by entering the exposure conditions. Furthermore, half-value layer, in-air exposure, and conversion factor can be calculated by using the newly developed software. This technique seemed to be sufficienlty useful if a user simply estimates'exposure dose.
