This work illustrates the ramifications of two different
approaches to tuning and exciting coils in a high-field
simulation environment: 1) forcing an ideal resonant
condition versus 2) specifying actual implemented lumped
element component values. This abstract uses the example
of a loop coil at 7T to demonstrate that results using
the second approach exhibit a more uniform current
distribution, more homogeneous |B

and 29% lower maximum 10-g average SAR. These results
illustrate that power/safety considerations of coils at
7T benefit from a simulation approach including
implemented component values rather than forcing ideal
resonance as typically simulated at lower field
strengths.
