A microstrip RF coil was designed
based on the Tic-Tac-Toe (TTT) concept. Simulations show similar B1+
distributions between the microstrip TTT and standard TTT coils, and experimental
data helps to validate the simulations.

simulation of standard TTT panel, b) simulation of microstrip TTT panel, c)
experimental B1+ map of microstrip TTT panel. Dashed
lines in (a, b) show central slices used in Figure 4.
