Abstract

The voxelized phantoms MASH and FASH have been used for calculating conversion coefficients (CCs) for a specific CT head examination performed in a specific Toshiba CT scanner. The X-ray spectrum was selected according to the concordance between the calculated C 100,c and measured C 100,c. For 120 kV, the X-raytbc code presented the smaller deviation, equal to −7.11%. Finally, effective doses calculated for the voxelized phantoms MASH and FASH were 6.1 and 4.5, respectively, smaller than the effective dose obtained though the European guidelines on quality criteria for computed tomography.
