The feasibility of integrating a whole-body X-nucleus birdcage in a wide-bore clinical 3T MR scanner is evaluated. The challenge is that this extension coil has to be tightly fit into the scanner bore, having a diameter just 16 mm smaller than the concentric 1H coil. Different configurations are proposed and evaluated with the purpose of minimizing interaction between the X-nucleus coil and the native 1H body coil of the scanner. Experimental results are in agreement with simulations and demonstrate a 1H coil detuning of 0.4 MHz due to co-integration with X-nucleus birdcage.
