Due to lack of dedicated fetal imaging coils, the standard commercial abdominal coil is often used for fetal imaging, of which the performance is limited by its insufficient coverage and element number. In this work, a dedicated 36-channel coil array for fetal imaging was designed, capable of covering a range of pregnancy from 20 to 37+ weeks. Compared to a commercial abdominal coil array, the proposed 36-channel fetal coil provides improved performance in SNR, parallel imaging capability, and image quality.
