We developed an 8-element transceiver fractionated dipole array, combined with a detunable 16-element receive-only loop coil array and evaluated it by prostate imaging on six volunteers (BMI 22-32.8). Reflection and coupling levels are low for all investigated subjects. B1+ amplitude in the prostate (after B1 shimming) ranges from 10 T (BMI 32.8) to 15.4 T (BMI 22). T2w prostate images are of good quality. The SNR of this design is better than for a design with antennas only (27 vs. 22). The good imaging performance with extended acceleration potential make this array an attractive design for body imaging applications.
