Device engineers and physicians can use the simulation results to understand exactly how energy is absorbed by the body and validate designs and treatment protocols. Designing an efficient, high-resolution MRI scanner for example requires an understanding of multiple overlaying fields at a wide range of frequencies – from the static magnetic field to the radio frequency pulse – and their complex interaction with the molecules of the body.Įlectromagnetic simulation models the propagation of waves through the body, and the interaction of waves with tissues – whether this is a desired therapeutic effect or an unwanted side effect. Medical devices such as magnetic resonance imaging (MRI), microwave imaging, and diathermy all rely on EM fields to operate. SIMULIA simulation technology also includes accurate bio-heat models, taking into account thermoregulation effects such as blood flow and metabolic heat, to realistically simulate how electromagnetic fields heat the body. A family of simulation-ready human body models representing different body types is available from SIMULIA. SIMULIA software supports both polygonal (CAD) body models and voxel body models, which can be posed within the tool to set up realistic test scenarios. The complexity of the human body requires very detailed simulation models. High-performance solver technology can simulate EM fields in the complex environment of the body rapidly and accurately. Powerful design tools and realistic material models can capture the rich details both of electronic devices and the human body. The electromagnetic and multiphysics simulation tools from the SIMULIA brand of Dassault Systèmes can be used to tackle the challenges of electrical engineering in the vicinity of the human body. The human body is an extremely complex structure made up materials with a wide range of EM and thermal properties, meaning that specialized modeling and simulation tools are needed. Safety regulations mean it is also a concern for a huge range of other products ranging from smartphones to electric cars. This makes it a crucial topic for a wide range of medical devices for imaging and treatment. Bioelectromagnetics covers the interaction of electromagnetic fields with the human body.
