In this study a 8+4-channel receive phased array for optimized MRI of newborns and premature infants at 1.5T was developed. State of the art MRI coils are mostly designed for adults and suitable to only a limited extent for pediatric and newborn imaging. Several challenges like imaging of small objects with high resolution and accelerated imaging to prevent motion artifacts can be met by using an adapted phased array. It provides high signal-to-noise-ratio and the possibility for accelerated imaging. The very compact design allows using the 8+4-channel array system in a MR safe incubator to minimize environmental stress.
