Synopsis
To improve the SNR in deep brain of human head images acquired using RF coil arrays with high coil element count, we proposed a 32-ch coil array with enlarged and over-overlapped coil loop elements laid out on a semi-flexible 3D-printed coil former. The experiment results showed that both the overall homogeneity of images and the SNR in deep brain are significantly improved.
