Clinical pediatric MRI is often performed using receive coils designed for adult patients. The mismatch of the receive coils and the pediatric patients can cause degraded image quality. In this work, a 64-channel receive-only phased array dedicated for pediatric body MRI is designed and constructed. This coil array incorporates the quarter-wavelength-balun technique, achieves ideal coil decoupling, and is very flexible in one direction conforms to different pediatric patient sizes. Here, we validated the performance and flexibility of the coil array in phantom and in vivo studies.
