Bilateral Orthogonality Generating Acquisitions Method for Homogenous Balanced Steady-State Free Precession at 7T

Motivation: Elimination of the transmit field inhomogeneity effects in the brain for T2 contrast at 7T. Goal(s): Removing the transmit field inhomogeneity effects in balanced steady state free precession acquisitions using Bilateral Orthogonality Generative Acquisitions method. Approach: Bilateral Orthogonality Generative Acquisitions method is implemented at dual channel parallel transmit 7T system using several balanced steady state free precession acquisitions with varying scan parameters to eliminate the transmit field inhomogeneity effects and reduce the banding artifacts effects via different combining schemes in the final image. Results: T2 contrast was obtained without the transmit field inhomogeneity effects but residual banding artifacts exists in the final images. Impact: T2 contrast can be achieved without the transmit field inhomogeneity effects in the brain using balanced steady state free precession sequence.
