This work compares the performance of a 3 channel
transceive
31
P
surface coil with a comparable sized 16-leg birdcage for
the application in
31
P
localized spectroscopy experiments in the human calf at
7T with 3D electromagnetic simulation. B
1
+
as
well as SNR calculation for a comprehensive
investigation is presented for both designs, showing
higher B
1
+
and
SNR in the regions of interest for the surface coil,
while as expected the birdcage exhibits better
homogeneity. Since the ROIs are small voxels the
advantage of better homogeneity is of minor importance
compared to high sensitivity in terms of B
1
+
and
SNR.
