Figure 6. Transmission fields (B₁ ⁺) of the hybrid applicator at 7.0 T in the human brain.

In vivo brain B₁ ⁺ maps obtained from Bloch Siegert mapping of the eight independent channels of the applicator (left). For B₁ ⁺ mapping an axial slice through the subject's brain was used. The colour scale is in units of 16 µT/√kW. B₁ ⁺map of the volunteers brain after B₁ ⁺ shimming (right). The B₁ ⁺map shows rather uniform B₁ ⁺distribution.
