Dynamic B 0 shimming for multiband imaging using high order spherical harmonic shims
PurposeTo describe and implement a strategy for dynamic slice‐by‐slice and multiband B0 shimming using spherical harmonic shims in the human brain at 7T.TheoryFor thin axial slices, spherical harmonic shims can be divided into pairs of shims (z‐degenerate and non‐z‐degenerate) that are spatially degenerate, such that only ½ of the shims (non‐z‐degenerate) are required for single slice optimizations. However, when combined, the pairs of shims can be used to simultaneously generate the same in‐plane symmetries but with different amplitudes as a function of their z location. [...]

Model-based system engineering (MBSE) provides a high-level environment and efficiently handles the ever-rising complexity of computation and control systems. We introduce a requirement-driven, model-based development methodology (RDD & MBD) for real-time computation systems based on vendor neutral specifications. [...]
