Automatic tube current modulation is meanwhile a standard procedure in modern CT devices to save radiation dose. The implementation of this method into Monte Carlo organ-dose calculations is described. A comparison of conversion coefficients obtained with and without tube current modulation is performed. A standard reliable procedure to compute conversion coefficients for any CT examination is to combine the pre-computed coefficients obtained in axial scans appropriately. The applicability of this procedure was validated for the case with tube current modulation, too.
