Assessment of a PML Boundary Condition for Simulating an MRI Radio Frequency Coil
Figure 6
Measurement of homogeneity of field. (a) Acquired MR image
of an oil phantom loaded within the coil. (b) Calculated -map
after 40-cycle iterations with and . The
homogeneity of -map is good inside, on the surface of, and outside
of the coil. (c) Calculated -map after 40-cycle iterations with
and . The homogeneity of -map is unacceptable. (d)
Calculated -map after 120-cycle iterations with
and . The intensities of the field at the
left-bottom corner and right-top corner are higher than those at other corners.
