Comparison of the mean stomach doses expressed as percentage of the prescribed dose (%) between the actual patient’s images and the predicted phantoms for three selected patients with different BMI values: 18.2 kg/m2 (A), 21.6 kg/m2 (B) and 33.2 kg/m2 (C), and for the ICRP male phantom taken as reference.
