Interaction of the human body with electromagnetic fields is widely used in medical devices for both diagnosis and therapeutic purposes. Over the last decades there has e.g. been a continuous trend to replace X-ray-based devices in favor of EM-based ones. Additionally, wireless communication of implanted devices is gaining importance. The main challenge during the development of such devices, is the detailed understanding of the field distribution inside the body, since measurement inside living organisms is almost impossible. Here, simulation can be of great benefit. In this webinar we show that human body models have evolved to the point where both the electromagnetic radiation effects as well as macroscopic effects, such as heating, Specific Absorption Rate (SAR) distribution, etc. can be predicted with CST® tools. Through the appropriate selection of a body model, it is possible to personalize medical treatment plans and greatly improve diagnosis tools without the need for excessive invasive testing. Using several examples, we will show the toolbox of features related to biomedical simulations which are available to the user of CST STUDIO SUITE®. These include the calculation of field distributions inside and the power absorbed by the body and thermal effects due to these fields.

With electromagnetic and thermal simulation, RF coils can be designed to produce safe, homogeneous fields that comply with SAR legislation, even in the complex environment of the human body.
Simulation of Implanted Medical Devices
We will discuss using simulation to design small implanted devices to be used in a geometrically complex electrically large environment: the body. The topics include dieletric and thermal material properties, choice of numerical method, HPC, and field...
Analyzing HF & LF RadHaz Scenarios with 3D EM Simulation
Standards exist to regulate device design and installation of antennas and high-power components to avoid exposing people to radiation hazard problems. As measurement is typically not an option inside the human body, EM simulation is often the only...
Using Simulation to Calculate the SAR of a SAM Phantom Head Model with Mobile Phone
This example demonstrates the ability of simulating for Specific Absorption Rate (SAR) in biological tissues such as a human head model (SAM). Arbitrary structures such as mobile phones may be defined using the powerful user interface in CST MWS or its...
Assessment of Occupational Exposure of MRI Workers Resulting from a Time-Varying Magnetic Field Associated with a Cylindrical Z-Gradient Coil
The exposure of staff in the vicinity of MRI scanners to low frequency (~ 1 kHz) time-varying fields associated with gradient coils is currently of interest in view of limits prescribed in the European Union Directive 2004/40/EC (1) due to be legally...
