Non-resonance 16-element transceiver array for human head imaging at 7T

Decoupling issue is a challenging problem in transceiver array designs at high fields. The Non-resonance RF method (NORM) using traveling wave provides a promising way to alleviate this problem and also has multi-frequency excitation and reception capability. In this work, a 16-element transceiver NORM array for 7T human head imaging is modeled and simulated using FDTD method. The unmatched decoupling and excellent g-factors were achieved, indicating the feasibility of parallel imaging using the proposed NORM array. The same NORM array is able to perform multinuclear excitation and detection, such as C13 and P31, which is verified by FDTD simulation.
