Ultimate intrinsic SNR has been introduced to establish an upper limit for physically achievable SNR in MRI. Up to now, due to computational complexity, ultimate intrinsic SNR solutions have only been presented for highly symmetric and homogeneous phantoms. Using 3D field simulations, we have evaluated ultimate intrinsic SNR for the human head at 9.4T allowing comparison of novel conductor arrangements for high field, parallel imaging coils and evaluating experimental performance in an absolute measure. Simulation results using a human head model (Ella) are presented.
