    摘要： A pediatric magnetic resonance (MRI) system and sub-system are provided. The pediatric MRI system includes a magnet-gradient assembly, an RF shield-body coil assembly and a pediatric MRI sub-system. The pediatric MRI sub-system includes an infant warmer or isolette having a patient section for accommodating a patient. The infant warmer is positionable relative to the magnet-gradient-body coil assembly of the pediatric MRI system. The pediatric MRI sub-system also includes a warming mattress arranged within the patient section of the infant warmer. The infant warming mattress includes an interior space filled at least partially with a host medium and a conduction heating system at least partially arranged in the interior space to conduct heat to the interior space of the infant warming mattress. The pediatric MRI system also includes at least one local radio frequency (RF) coil that is positionable within the patient section of the infant warmer.

    摘要： An ambulance-compatible magnetic resonance imaging (MRI) system for on-site emergency diagnosis includes a mid-field super-conducting head-only magnet including a bore and an active shield arranged relative to the magnet, a passive shield arranged relative to the magnet, the passive shield including a first flange arranged adjacent to a first side of the magnet bore, a second flange arranged adjacent to a second side of the magnet bore, wherein the first flange and the second flange are electrically connected to each other, and wherein the passive shield is operative to capture flux extending out from the magnet bore and return the flux to the magnet. An asymmetric head gradient assembly for generating magnetic gradient field in the mid-field super-conducting magnet is also provided, the magnetic gradient field being between 100-150 mT/m or having a slew rate between 400-800 T/m/s. The MRI system includes a receiver coil and a controller operatively coupled to the receive coil, the controller configured to produce an image based on data obtained from the receive coil. The MRI system is mountable in an ambulance vehicle.
