Figure 6: Measurement of homogeneity of 𝑁 𝑝 = 1 0 field. (a) Acquired MR image of an oil phantom loaded within the coil. (b) Calculated 𝑁 𝑠 = 1 0 -map after 40-cycle iterations with 𝐵 1 and 𝐵 1 . The homogeneity of 𝑁 𝑝 = 1 0 -map is good inside, on the surface of, and outside of the coil. (c) Calculated 𝑁 𝑠 = 1 -map after 40-cycle iterations with 𝐵 1 and 𝐵 1 . The homogeneity of 𝑁 𝑝 = 1 0 -map is unacceptable. (d) Calculated 𝑁 𝑠 = 1 0 -map after 120-cycle iterations with 𝐵 1 and 𝐵 1 . The intensities of the 𝑄 field at the left-bottom corner and right-top corner are higher than those at other corners.
