Developing of voxel phantoms has been an active field of research during the last decades and is receiving more attention nowadays. Reference phantoms for several ethnic groups have been developed recently as an extension to the ICRP reference phantoms that are based on Caucasian standard anatomical data,. This work reports an attempt to develop a tool for automatic slice-based adjustment of voxel phantoms. This tool achieves the adjustment process depending on anthropomorphic data extracted from anterior and lateral images for targeted body. The software was used to adjust Golem voxel model according to 23 Sudanese individuals. The weight, height, and age of these individuals vary from 52 to 113 Kg; from 166 to 188 cm and from 20 to 35 years, respectively. The maximum equivalent diameter, mean equivalent diameter, major axis length, minimum axis length, solidity and volume of brain, heart, kidneys, liver, lungs, spleen and bladder were calculated for all prepared models. For each organ, the mean value for each of these parameters was calculated and the deviation of each model from this value was evaluated. For the obtained data, we have calculated a global deviation of model (GDM) and selected the model with the smallest GDM to be the Sudanese voxel model. We have also compared volume, height and weight for 17 organs of the Sudanese voxel phantoms with ICRP phantom Golem ، visible human and voxel man model.
