Imaging of the human body by electromagnetic field based techniques like MRI has become a routine part of medical investigations. But the effect of implanted devices – both active (e.g. pacemakers) and passive (e.g. stents or artificial joints) – on image fidelity and imaging safety cannot be predicted without simulation.

A critical concern is the safety and reliability of these implanted devices when they are exposed to electromagnetic fields. The devices must function without interruption or failure, and their presence may not lead to unsafe field levels and the related resulting temperature increases which may cause cell damage. Since non-invasive measurement options for devices in living tissue are very limited, simulation plays an important role in predicting these effects and thus allowing the design of safe implantable devices.

In the near future, an increasing number of implanted medical devices, like pacemakers or neural stimulators, will see their size drastically reduced and reliability increased by wirelessly powering them from outside the body. 

With this eSeminar, learn about:

• The simulation challenges and solutions for designing small implanted devices in the context of a geometrically complex electrically large environment – the body.
• The correct definition of complex dielectric and thermal material properties, and a suitable choice of numerical method and high performance computing options, as they are critical for obtaining accurate results in as short a time as possible.
• The visualization of field results and generation of relevant results in post-processing as they are important for the engineer to understand and improve the device being designed.
