title: Determination of voxel phantom for reference Taiwanese adult from CT image analyses.
abstract: The International Commission on Radiological Protection Publication 103 recommended that ionising radiation doses should be assessed based on voxel phantoms. An anthropomorphic voxel phantom for the Reference Taiwanese Adult was built from analyses of computed tomography (CT) images. Thirty representative adult individuals were selected from normal patients in the hospital, with body mass index between 19.6 and 25.6 for males and 18.8 and 27.0 for females and body height between 163 and 175 cm for males and 152 and 162 cm for females. The Reference Taiwanese Adult was determined from these individuals by analysing their CT images for parameters characterising the size, position and orientation of several organs. Analysed parameters included the volume, surface area, major and minor axes, mean chord length, position relative to the body centre, and orientation with respect to the body axis, for liver, spleen, kidney, stomach, gallbladder and bladder. The person with the highest score was designated the Reference Taiwanese Adult.
