Development of skeletal systems for ICRP pediatric mesh-type reference computational phantoms

In 2016, the International Commission on Radiological Protection (ICRP) launched Task Group 103 (TG
103) for the explicit purpose of developing a new generation of adult and pediatric reference
computational phantoms, named ‘mesh-type reference computational phantoms (MRCPs)’, that can
overcome the limitations of voxel-type reference computational phantoms (VRCPs) of ICRP Publications
110 and 143 due to their finite voxel resolutions and the nature of voxel geometry. After completing
the development of the adult MRCPs, TG 103 has started the development of pediatric MRCPs comprising
10 phantoms (male and female versions of the reference newborn, 1-year-old, 5-year-old, 10-year-old,
and 15-year-old). As part of the TG 103 project, within the present study, the skeletal systems, one
of the most important and complex organ systems of the body, were developed for each phantom age and
sex. The developed skeletal systems, while closely preserving the original bone topolo...
