A 64chRx/16chTx head-neck-Cspine array coil was constructed and bench tested. A new UHF topology has been introduced, by merging two commonly separated array coil functionalities (Rx, Tx) at ultra-high field MRI into one anatomically shaped close-fitting housing. The ultimate two-folded goal of this study was to increase clinical benefit in ultra-high field neuroimaging through the extension of the brain region to the cervical spine and to decrease patient’s anxiety and discomfort using a patient-friendly coil design.
