Medical Device Analysis and Simulating Devices with the Human Body

Complex dielectric properties of in-vivo tissues can change significantly in different tissues as a function of frequency and water content. Using accurate and reliable simulation throughout the design process, broad range of post-processing results can provide your company several benefits, including a deep understanding of physcis, predicting performance of product, meeting safety standards, and product deadline.

Depending on application, detailed complex model (e.g. hyperthermia treatment) or simple equivalent models (e.g. specific absorption rate prediction of wireless products) are required. In ANSYS Electronics, a built-in library of various female/male body models are available. Further, detailed dispersive models of human tissues are available to be included in simulations.

Here are some applications of ANSYS electronics in healthcare applications:

  • A large library of complex dielectric properties of human tissues
  • Various positions of body models:
    • Small, medium and large body shells
    • Cerebral spinal fluid (CSF) models
    • Femoral implant models
    • Posed shell models
  • Full wave simulation of tissue tobtain EM power absorbed by the tissue
  • Broad range of materials can be modeled: homogenous, inhomogeneous, dispersive (Frequency-dependent), …
  • Studying a biomedical device transmitter design meets Federal Communications Commission (FCC) standards
    • Implanted antennas
    • Wearable devices
    • High power communication links
    • Portable wireless devices

Electrically Large Models and Hybrid Solvers

ANSYS solvers are continuously evolved to become faster and handle larger problems with complicated excitations and boundary conditions. Finite Element Method (FEM) is the main solver of ANSYS Electronics. In addition to FEM, HFSS-IE solver uses the method of moments (MoM) technique and physical optics (PO) to solve for the sources or currents on the surfaces of conducting and dielectric objects in open regions. HFSS-IE is effective for radiation and scattering studies of large, mostly conducting structures.

Another advanced solver is HFSS Savant that provides fast and accurate prediction of installed antenna patterns, near-fields and antenna-to-antenna coupling on electrically large platforms. (from ANSYS website). It is possible to use multiple or hybrid solvers for different regions of a simulation.

Here is a list of state-of-the-art solvers available in ANSYS:

  • Finite Element Method (FEM)
  • Method of Moments
  • Eigen mode
  • Linear Circuit Simulation
  • Transient Circuit Simulation
  • RF Circuit Simulation
  • Shooting and Bouncing Ray

Optimization, Parametric Study, and Sensitivity Analysis

The first step in an analysis process is simulating the performance of a base design.

Next step, various parameters of the base design can be studied to find their effect on the overall performance of the system for example parametric study of various parameters, optimization of one or multiple design goals, sensitivity analysis to identify the most important design parameters and their influence on the output, and tuning one or multiple parameters to achieve the design goals.

As a simple example, the geometry of an antenna can be optimized to resonate at the frequency of interest, maximize its radiation gain, and minimize impedance matching losses.

Low Frequency Electromagnetic Analysis

When the size and dimensions of a problem is extremely smaller than the wavelength, the low frequency family of ANSYS electronics is the most suitable option for simulation. The low frequency family has been tailored to meet requirements of static, quasi-static, or transient analysis of problems. Various solvers, excitations, boundary conditions, and built-in models are available to provide a user-friendly tool for such simulations, for example:

  • Low frequency electromagnetic including motion simulation
  • Electromechanical applications
  • Network analysis for systems analyses using Simplorer
  • Linear or rotational actuators
