Method of images 3D rendering of a level 1 mirroring of a surface mesh. The original mesh is gray colored with one side highlighted in violet. Mirrorings of this mesh are rendered transparent but mirrorings of the highlighted side are again highlighted in orange. The edges of the MSR are rendered in black. In the center, inside the original mesh, a black sphere with diameter 0.6 m is rendered, it depicts the target volume of our coil optimization. 3D models of different mirroring levels are depicted in the supplementary material.
