The aim of this study is a hardware related approach to increase the subject’s compliance for fMRI with awake infants. An infant-friendly head coil array was developed to improve sensitivity, spatial resolution, accelerated encoding, motion insensitivity, and subject tolerance in pediatric MR-imaging. The coil was characterized with both bench and image metrics and compared to a 32-channel adult head coil. The size-optimized 32-channel infant array coil provides increased reception sensitivity and is well-suited for highly accelerated fMRI data acquisitions in awake infants.
