Dissolved phase hyperpolarised 129Xe is an emerging technique for perfusion imaging in the brain using inhaled gas as a perfusion tracer. As the dissolved 129Xe signal is inherently weak when compared to the gas phase signal, RF coil sensitivity is critical for high SNR 129Xe brain MRI. In this work, the design, development and testing of a novel 6 channel receiver and birdcage transmit coil RF system for dissolved phase 129Xe MRI in the human brain at 3T is demonstrated.
