To improve accessibility of MRI and to enable advanced studies on motor coordination, we are part of the U01EB025153 collaboration to develop a compact 1.5 T head-only scanner enabling free limb movement. The compact size of the magnet significantly increases B₀ inhomogeneity, necessitating the use of novel imaging concepts robust to B₀ inhomogeneities that in turn require advanced B₀ field modeling capabilities. Here, we introduce a 31-coil Multi-Coil (MC) design capable to generate linear and non-linear MR image encoding fields as well as complex B₀ shim fields with low space and power requirements.
