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.
