Analysis of body segments using bioimpedance spectroscopy and finite element method
ABSTRACT: Elderly people and geriatric patients often suffer from dehydration which can be diagnosed by bioimpedance spectroscopy (BIS). In this work, the capability of segmental BIS to reflect the total body composition is analyzed. Therefore, measurements of body segments have been simulated using the finite integration technique (FIT) and the results have been verified by measurements on subjects. We show that results obtained from segmental BIS measurements correlate with wholebody bioimpedance spectroscopy measurements. Furthermore, simulations of segmental BIS have been successfully accomplished and the simulation results show similar characteristics compared to measurements performed for reference.
