Abstract
Parallel magnetic resonance imaging is limited by the SNR of the MR-signal detected by an antenna array. To fully exploit the SNR of circular surface loops surrounding a spherical head phantom, we developed an optimization routine to minimize the array's noise enhancement. We optimized the positioning of each array element and investigated the optimal loop radius. As a result we show optimal setups for 8, 16 and 32 array elements at 400 MHz with different rates of k-space undersampling.
