Abstract :
Modern open MRI systems have far more electromagnetic (EM) interaction with the environment than conventional cylindrical-bore systems. An EM simulation of an open MRI system has to include the entire examination room as well as detailed objects like internal body organs. This paper will discuss simulations involving an open MRI system and a heterogeneous human-body model. Validations with measurements will be presented.
