Element-tilted transceiver array was proposed for ultra-high field human studies. An 8-channel microstrip and an 8-ch loop array were fabricated for human knee at 7T. In those arrays, each element was tilted with a certain angle for achieving sufficient decoupling without using dedicated decoupling networks. Our result showed that decoupling was significantly improved (better than 18dB) for both arrays, and the B1 field is also increased (better than 20%) in the imaging region for the microstrip array compared with non-tilted case.
