This abstract describes our experiences implementing a volume transmit, local receive setup for cardiac ³¹P-MRS on a Siemens research 7T MRI scanner. Two strands of development work have been performed in tandem: (i) development of a fully removable whole-body transmit RF-coil and testing with the standard 8kW RFPA and SAR monitoring and combined with a 16ch receive array, and (ii) integration of a 35kW RF power amplifier, a new energy chain, and adapted SAR monitoring.
