Imaging premature and neonatal babies in incubators is challenging due to time constraints, motion artifacts and the need for high resolution. These issues call for increased detector sensitivity to achieve high spatial resolution and highly-parallelized array image acquisition. In this work we have constructed and tested two 16-channel brain arrays sized for roughly 32 and 36 weeks gestational age as well as a 32-channel array for term neonates. The SNR and g-factors of these arrays are compared to each other and to an adult sized coil.
