Recently a high-quality voxel model of a Korean adult male was constructed at Hanyang University by using very highresolution serially-sectioned anatomical images of a cadaver, which was provided by the Korean Institute of Science and TechnologyInformation (KISTI). Most existing voxel phantoms are developed based on an individual in the supine posture. This study convertedthe HDRK-Man voxel model into surface model and adjusted the flattened back of the HDRK-Man to a normal shape in the uprightposture using 3D graphic softwares such as 3D-DOCTORTM, Rapidform2006, Rhinoceros4.0, MAYA8.5. The effective doses ofadjusted model were compared with those of unadjusted model for some standard irradiation geometries (i.e., AP, PA, LLAT, RLAT).In general, the differences were not very large and, among those, the largest difference was found for the PA radiation geometry, asexpected. These methodologies can be used for the development of various deformed posture models of HDRK-Man in the later stageof this project.
