The B1+field homogeneity, SAR and SNR of shielded birdcage, TEM and microstrip volume coils are compared at 7T in this work by finite difference time domain (FDTD) method. It seems that the birdcage coil has the best unload B1+ homogeneity but the TEM has the best loaded B1+ homogeneity. On the other hand, the microstrip coil seems better in terms of SAR and average SNR than other two coils at ultra high field MRI.
