For MRI RF volume coil simulations, we analyze the effect of the size of the loaded body model on the calculations of power deposition, specific absorption rate (SAR), and B1+ field distribution. This is accomplished by loading a TEM resonator with five body models that are identical except for the number of cells each contain in the direction orthogonal to the axial plane. We calculate various parameters relevant to the aforementioned issues in the five cases to determine the approximate cutoff size required to achieve accurate results.
