Example Model

A generic seven Tesla birdcage head coil with generic phantom with average head tissue parameters is used as an example to illustrate the MRI application macro features.

The birdcage MRI coil has two ports at the bottom rung. They are excited with equal magnitudes and 90° phase difference. Both rungs have sixteen equal-value capacitors, which tune the resonance of the system. The coil's diameter is 30 cm. Around the coil is a cylindrical shield. The birdcage coil is aligned with the Z axis.
