Inhomogeneities across large FOVs are problematic at ultra-high field. We propose a software-based TIAMO implementation to enable similar flip angles across the body without hardware interference on the 7T MR scanner. Using an interleaved and complementary CP+/CP2+ excitation scheme, we acquired water-selective and lipid-selective 3D GRE data at high resolution demonstrating homogeneous signal distribution across the pelvis and lower abdomen.
