This abstract presents the development of a 3 channel

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.
