Model for 𝐵₁ Imaging in MRI Using the Rotating RF Field

Figure 5

Measurement vector 𝐷 for 𝑁×𝑀=80×80 image. Shown are both amplitude and phase values obtained with (1). The RF coil was rotated 80 times while each time a different strength 𝑔_𝑛 of the 𝐵⁺₁-field was applied (with a total of 80 values spanning the range [𝑛−𝑀/2−1/2]).
