The combination of highly flexible RF coils and on-coil shimming is an interesting concept, in particular for applications in body parts that have strong inter-patient variability, such as breast, thorax or abdomen. The well-known AC/DC approach on rigid standard loop coils involves many bulky RF chokes and would therefore not be suitable for flexible coil elements. In the presented approach coaxial coils are used instead, where no segmenting capacitors and correspondingly no RF chokes are required. We demonstrate that this conceptual design shows good RF performance and the created magnetic fields for shimming are in good agreement with analytical calculations.
