We use three fabrication techniques to manufacture dual-channel receive coil arrays: (1) single-layer casting, (2) double-layer casting, and (3) direct-ink-writing. All fabricated arrays perform equally well on the bench and produce similar sensitivity maps. The direct-ink-writing method is found. Abstract: Flexible and stretchable radiofrequency coils for magnetic resonance imaging represent an emerging and rapidly growing field. Measurements on the shape of the tooling at the different stages included in the process 5. Coil size uniformity - Importance 6.
