In this study, a semi-flexible 32-channel RF coil array was developed for clinical brain imaging. In this coil, a semi-flexible mechanical structure was used to minimize the gap between the head and coil elements for different patients. The alignment of 32 coil elements was optimized to minimize the coil loss and overall coupling. It was demonstrated that this coil gives lower SENSE g-factor and higher SNR in depth compared with a standard eight-channel clinical RF coil in clinical brain imaging applications.
