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.
