Tailoring RF Power Distribution for Body Torso MRI at 300MHz

Jinfeng Tian¹, Anand Gopinath, J. T. Vaughan

Simulation and image experiments suggested low |B1+|/Power in 7T body-torso imaging, partly due to radiation and undesired power losses in the rest of the body. Three dielectric methods were proposed based on the electromagnetic wave incidence theory, and verified with Finite-Difference-Time-Domain simulation, with a 16-channel body-size TEM array.
