Abstract
Potential sanitary effects related to electromagnetic fields exposure raise public concerns, especially for fetuses during pregnancy. Human fetus exposure can only be assessed through simulated dosimetry studies, performed on anthropomorphic models of pregnant women. Only few pregnant women models have been previously proposed, representing multiple stages of pregnancy. In this paper, we propose a new methodology to generate a set of detailed utero-fetal unit (UFU) 3D models during the first and third trimesters of pregnancy, based on segmented 3D ultrasound and MRI data. UFU models are built using recent geometry processing methods derived from mesh-based computer graphics techniques and embedded in a synthetic woman body. A set of nine pregnant woman models has been generated using this approach and validated by obstetricians, for anatomical accuracy and representativeness. These models enable, for the first time, the study of the influence of pregnancy stage, fetus position and morphology on dosimetry.
