      abstract     = {A 32-channel parallel transmit (pTx) add-on for 7 Tesla
                      whole-body imaging is presented. First results are shown for
                      phantom and in-vivo imaging.The add-on system consists of a
                      large number of hardware components, including modulators,
                      amplifiers, SAR supervision, peripheral devices, a control
                      computer, and an integrated 32-channel transmit/receive body
                      array. B1+ maps in a phantom as well as B1+ maps and
                      structural images in large volunteers are acquired to
                      demonstrate the functionality of the system. EM simulations
                      are used to ensure safe operation.Good agreement between
                      simulation and experiment is shown. Phantom and in-vivo
                      acquisitions show a field of view of up to 50 cm in
                      z-direction. Selective excitation with 100 kHz sampling rate
                      is possible. The add-on system does not affect the quality
                      of the original single-channel system.The presented
                      32-channel parallel transmit system shows promising
                      performance for ultra-high field whole-body imaging.},
