Electromagnetic modeling has been widely used to study MRI RF coils, but the coil model usually only consists of conductors and lumped elements. The impact of mechanical components (such as coil housing, patient table) has not yet been thoroughly investigated. This work showed that including mechanical parts in the model lead to noticeable changes of total B1 and E fields (up to 15% and 32% increase respectively in the central axial slice), peak SAR (22%), and coil input power (67%) calculations.
