At 7T, parallel transmission (pTx) systems provide still significant challenges for the design and implementation of RF-coils for dedicated transmit channels and their integration into existing pTx systems. This work was focused on the construction of a 16-channel head-array for available combined 8-channel and individual 16-channel transmission systems, resulting in a RF-coil with a total of 8-channel pTx system. Flip angle (FA) maps of an oil and water phantom were acquired using this prototype. For 16 individual FA maps for odd-even channels and 8 combined FA maps of 16-channel head-array were compared with RAPID Biomedical 8-ch. Tx/Rx head-array at 7T.
