Abstract :
This paper provides RF coil studies at ultra high field MRI. The results and conclusions are based on experimental findings with MRI systems and computational electromagnetics using the finite difference time domain method. The outcome of these studies is then utilized to provide new avenues and techniques to improve the performance of RF head/body coils for human MRI at very high fields
