Advances in Female Chest Modeling: Enhanced 3D Dosimetric Models Across Two Illustrative Scenarios

Area of Science:

• Computational dosimetry and bioelectromagnetics.
• Development of advanced virtual human models for exposure assessment.

Background:

• Accurate electromagnetic field (EMF) exposure assessment relies on image-based virtual human models.
• Conventional 3D female models lack realistic breast anatomy due to imaging posture limitations, impacting EMF simulations.

Purpose of the Study:

• To develop an anatomically realistic female virtual human model with an improved breast geometry for EMF exposure simulation.
• To address the critical gap in simulating EMF exposure in the female chest area.

Main Methods:

• Developed a novel breast model with natural upright geometry.
• Integrated the enhanced breast model into an existing whole-body virtual human model.
• Tested the model in radiofrequency plane wave and low-frequency magnetic stimulation scenarios.

Main Results:

• The enhanced model demonstrated significant differences in localized field distributions compared to conventional models.
• Realistic upright breast anatomy impacts EMF exposure calculations.

Conclusions:

• Anatomical accuracy, particularly of the breast, is crucial for precise EMF simulations.
• Findings support the need for more anatomically faithful virtual human models in computational dosimetry for regulatory, occupational, and clinical applications.
