Abstract :
With the development of miniaturized wireless wearable and implantable medical devices, pervasive monitoring is becoming a clinical reality. With an increasing drive for minimizing power utilization, optimal antenna design and radio wave propagation are important topics for BSN (body sensor networks) research. To this end, subject-specific modeling is essential for achieving a truly personalized and optimized sensor design. In this paper, a Volumetric Graph Laplacian method is used for subject-specific whole-body mesh warping for finite-difference time-domain (FDTD) simulations. Validation of the method is shown with data from both phantom and MR studies with FDTD simulations.
