This paper presents the initial in vivo imaging results from a new unilateral 8-channel pTx transceive array designed and constructed for 7 T MRI of the hip joint. With subject-specific RF shims, 3D sequences (DESS and MEDIC) provided sufficient coverage, uniform image intensity and excellent contrast. The RF techniques employed in the construction of the array promote efficient use of RF power, enabling turbo spin echo sequences with full coverage of hip joint to be performed with adequate excitation. Comprehensive and conservative RF safety procedures ensure that local RF energy absorption is well below regulatory limits.
