In this study we designed a 17O phased array coil (17O-PA) with 30 17O receive elements and a 17O transmit coil for 17O brain imaging at 7Tesla. The improvement in imaging quality achieved by a 17O phased array coil system can then be used in future patient studies to improve the image resolution or to shorten scan times during inhalation of the 17O-gas.
