A size-adaptable receive array that can accommodate a variety of heads in a pediatric population (27-week-premature to 1.5-month-old) is proposed. Thirteen spherically distributed loops can move in radial and axial directions to maximize their proximity to the subject. Decoupling between elements is ensured by strong preamplifier decoupling (-27 to -33 dB). Tests on a scanner with two phantoms (8 and 10 cm in diameter) resulted in higher SNR with the proposed coil compared to 8-Ch and 32-Ch commercial head coils. The method restricts head motion and could be of interest for other size-varying body parts, such as breast and limbs.
