In this work a design study of a shoulder cut-out gradient coil for use in a head-only MRI platform was performed. Specifically, based on previous work, it explored the effect of rotating the gradient axes on performance. This was due to the imbalance of gradient performance degradation due to the presence of cut-outs on conducting surfaces next to the patient's shoulders. This proof-of-concept exploration is the first demonstration of the feasibility of rotating the gradient axes during the design process to design a shoulder cut-out gradient coil.
