We propose a flexible coil array design
consisting of circumferential shielding stacked on circular coils to achieve
robust decoupling between coil when the array is either bended or on a
flat plane. Two types of circumferential
shielding were tested through numerical simulation. The results demonstrated
that both types can have good decoupling on a curved surface with S21
< -17.1 dB. The maximum |B1| for the array coil with Type-II (two-parallel-ring)
shielding was 63% larger than that with Type-I (single-strip) shielding. Future
work will empirically construct these coils to compensate simulation inaccuracies
and validate their performance In Vivo.
