Large improvement in <scp>RF</scp> magnetic fields and imaging <scp>SNR</scp> with whole‐head high‐permittivity slurry helmet for human‐brain <scp>MRI</scp> applications at 7 T
The RF coil sensitivity and MRI SNR were largely improved with the two-piece HPM slurry helmet demonstrated by both electromagnetic simulations and in vivo human head experiments at 7 T. The findings demonstrate that incorporating an easily producible HPM slurry helmet into the RF coil array significantly enhances human-brain MRI SNR homogeneity and quality at ultrahigh field. Greater SNR improvement is anticipated using the less lossy HPM and optimal design.
