Due to lack of dedicated fetal imaging RF coils, the system body coil is often used to acquire fetal images. This setup is not optimized and offers limited sensitivity and image quality. In this work, we designed and manufactured a 22-channel flexible coil array for fetal examinations. Compared with Siemens 6-channel body coil, the proposed fetal coil array achieves significant improvements in imaging coverage, image SNR and parallel acceleration capability.
