Calculated dose values for the 8-year-old obese male abdominal CT scan. The results for the Absolute dose values calculated with MC-GPU for the extended patient anatomy simulation were compared with NCICT software for a whole-body computational phantom with similar height and weight to the patient and to an MC-GPU simulation for the same NCI phantom.
