Computed tomography (CT) is an imaging technique commonly used in Radiation Oncology clinics. Accurately determining the specific stochastic risks associated with low-dose ionizing radiation is challenging, so estimating the radiation dose is sometimes necessary. Various computer codes have been employed for this purpose, including the National Cancer Institute dosimetry system (NCICT) used in this study. The NCICT code combines International Commission on Radiation Protection reference pediatric and adult voxel phantoms with Monte Carlo simulation of the reference CT scanner to calculate organ doses for CT patients. This study aimed to investigate the effect of body mass index (BMI) on organ dose and effective dose. The doses received by certain organs were calculated using the NCICT code by varying the mass of a male phantom while keeping the height constant. As a result, changes in doses to the lung, kidney, liver, spinal cord, and the effective dose with respect to BMI were analyzed. It was found that the doses to the lung, kidney, liver, spinal cord, and the overall effective dose decreased as BMI increased.
