Within the framework of this study, four high resolution computer models of a woman, a man and two children will be developed. Whereas no anatomical models of children exist so far, the available models of adults which are used in numerical dosimetry are generally based on prediscretized voxels. Therefore they yield limited accuracy with respect to small details and can only be used in a predefined mesh. These restrictions will be overcome by developing the new models as based on CAD representations of all tissues and organs. Therefore they will yield unprecedented detail and accuracy, and they can be discretized at arbitrary mesh resolutions. The models will be generated using MR-images from the most advanced scanning system, and the images will be discretized by a team of biologists and CAD experts. The study is carried out in cooperation with the Food and Drug Administration, Washington DC, Siemens Medical Solutions, Erlangen, Germany, and the Friedrich-Alexander-Universität, Erlangen, Germany.
