In this work, we aim to find a better solution to fetal imaging. We studied a commercial available 8-channel torso array that is routinely used in clinical fetal imaging, and a proposed flexible 32-channel array. Our results show that, with the increased number of elements and the flexible design (leading to improved filling factor), the 32-channel fetal array demonstrates significant gains in SNR and B1 homogeneity in the whole uterus region, which ensures the performance of the fetal brain imaging regardless of the location of the fetal head in the uterus.
