In this work, an eight-channel transmit/receive loop array with induced current elimination (ICE) decoupling method was built and investigated to demonstrate its feasibility and robustness for human head imaging at 7T. This array has been validated through bench tests and in-vivo human head MR imaging experiments. Isolation between the adjacent loop elements is better than -25dB by employing this new design. The ICE-decoupled array also shows excellent parallel imaging capability that the average g-factor of human head in the sagittal plane was as low as 1.14 when acceleration factor achieves 4.
