dc.description.abstract | The proposed study reports the design and testing of spoke coil (SC), that compensates for the degradation in the g-factor that is caused by the insufficient sensitivity of the coil array along the main magnetic field direction. Electromagnetic (EM) simulations were performed to evaluate the performance of the proposed coil in a 7-T MRI system. 25-channel surface loop array and short dipole array containing SC or circular loop coil (LC) on the top of the phantom are 3D modeled. The SENSE g-factor and SNR of coil arrays are calculated and evaluated, and the quality factor (Q), scaling factor (), and noise-corelated resistance (R) are considered. The directed effective magnetic field (B-1(-)) generated by the SC improves the g-factor by compensating for the insufficient sensitivity information gathered by the array. However, this arrangement should be optimized to increase the available sensitivity information, depending on the type and structure of the coil elements in the array. | - |
