Compromising the size and shape of pediatric brain arrays so that one size fits all or using adult brain or knee arrays causes a significant degradation of SNR and parallel imaging performance compared to a coil of the appropriate size and shape for a given aged child. Unfortunately, rapid head growth in the first years of life requires either a flexible array approach or multiple sizes which span the size range with reasonable discrete increments. In this work, we developed and tested four incremental sized 32-channel receive only head coils for pediatric patients spanning an age range of 6 months to 7 years old. The constructed coils show significant SNR gains for both accelerated and unaccelerated imaging in pediatric brain imaging.
