We compared and characterized the RF field wave behavior for human brain imaging at 10.5T and 7T. Additionally we explored the feasibility of using monolithic high dielectric constant materials to potentially further enhance SNR and circumvent SAR limitations and show that there can be great benefits through phantom experiments and computer modeling.
