The current landscape of pediatric body MRI lacks dedicated high-density arrays, especially for small children. Therefore many centers use existing arrays designed for adults. These arrays are much larger than the patients, reducing the effective number of elements. Adult arrays are heavy for children and are supported by additional padding, increasing the distance from the patient and reducing image quality. Here, we present an appropriately sized blanket-like array designed from patient data for torso and chest/abdominal imaging of 0-2 and 3-5 year olds respectively. This pediatric array is fabricated using screen-printed electronics to produce an extremely lightweight and flexible coil.
