Coil-loop geometries were defined and simulated on electromagnetic (EM) software FEKO. Image intensity distribution was evaluated for different orientations with respect to B0. Overall, single loop and double loop with opposite current show complementary results. The switch between these two loops could be realized using MEMS (Micro Electro-Mechanical System) switches. This can reduce the dependency of the coil-sensitivity to its orientation with respect to B0 and can lead to the development of SwiM RE-coils (SWItches MEMS for Reconfigurable Endoluminal coils).
