Motivation: To explore the SNR performance of Loop and Sleeve antennas for multi-channel human head imaging at 10.5T.
Goal(s): Validation of achievable receive performance of loop and sleeve antennas with same number of channels.
Approach: Simulation based analysis of SNR between loop and sleeve antennas with same channels.
Results: We obtained and compared simulated SNR data of loop and sleeve antennas. For the same number of channels (1, 3, 5, and 32-channels), each SNR map was compared with similar imaging coverage. Our experimental data indicates an enhancement of SNR achieved with the 32-channel sleeve antenna array compared to the 32-channel loop array.
Impact: Our simulations indicate that a high-density sleeve antenna array compared to a classical loop array can achieve enhancement of SNR for human head imaging at 10.5T.
