Development of whole-body voxel human models

Pregnant woman voxel models

To simulate how the radio waves emitted from devices, etc., behave inside a pregnant woman's body and fetus and affect them, we have jointly developed with Chiba University a whole-body voxel human model of a Japanese woman in the 26th week of pregnancy. At present, this model is being distributed free of charge for non-commercial and/or research purposes.

A fetus voxel model (including tissues specific to pregnant women)

A fetus model created from a woman's abdominal MRI image

Resolution: 0.742 x 0.742 x 0.742 mm
Tissues: 6 types (fetus, fetal head, fetal eyeballs, amniotic fluid, placenta, uterine wall)

Free-Form Deformation is used to modify the abdomen of the adult female voxel model Hanako.

Pregnant woman voxel models

Pregnant woman voxel models are being developed by combining a fetus model and a female model whose abdominal area has been modified. Efforts are currently under way to develop whole-body voxel models, not only of women in the 26th week of pregnancy but also of various other stages of pregnancy. As with the other models, we plan to make them available to researchers.

Week of pregnancy: 26th week
No. of tissues: 56 types
Resolution: 2 x 2 x 2 mm
Abdominal shape: Matches the average value
