Magnetic resonance imaging (MRI) of the developing brain and heart could greatly benefit from the higher signal levels and improved tissue contrast at 7T. However, there are currently no dedicated RF coils and associated patient handling for young infants (<3-months). We describe design criteria and solutions to build the first mechanical frame and coil formers for imaging the brain and heart in infants up to 3-months of age in an integrated manner at 7T. The different parts incorporate important design aspects including mechanical sturdiness/safety, toxicity, sanitization and ease of use.
