7T 8-channel transmit/receive head volume coil is introduced which is capable
to produce transmit fields in the human brain of more than 50 µT necessary
for single voxel MRS with acceptable chemical shift artifacts. Key to this good
transmit field efficiency was careful design and material selection but also the
choice of relatively short coil elements. From the simulation based design process
appropriate input power limits were concluded which allow safe operation of the
coil in compliance with IEC 60601-2-33.
