Multiphysics Simulation of MRI Systems


On Demand

Discover the central role that multiphysics multiscale simulation has to play in MRI device design.

Magnetic Resonance Imaging (MRI) devices can provide very detailed images of the human body without applying any ionizing x-ray dose. Behind the scenes, MRI requires an advanced interaction of various electromagnetic (EM) fields. Thermal effects and mechanical forces also need to be known to have a successful design that meets the safety requirements.


With this eSeminar, learn about:

  • The use of the Biot-Savart method in Opera to obtain the required level of simulation accuracy
  • The consideration of superconducting coil overheating using Opera
  • The use of the Bioheat solver in CST Studio Suite as part of assessing the safety of the device
  • Coupling the EM results to a numerical spin simulator based on the Bloch equation
