This abstract presents the development of a 3 channel 31 P and 2 channel 1 H RF coil array for phosphorous spectroscopy in the human visual cortex at 7 T. The naturally low sensitivity of 31P spectroscopy requires very efficient RF hardware for a successful implementation of an experiment. The array was modeled and optimized with the help of 3D electromagnetic simulation and was build and tested on the bench with a network analyzer. Preliminary results were obtained inside the scanner (Siemens, ) with phantom and fruit measurements, showing good results.
