    摘要： In order to increase the signal to noise ratio, and thus increase the quality of images produced during pediatric MRI, a pediatric RF coil assembly includes a head coil and a flexible body coil in a single dedicated device shaped and sized for a child. The flexible body coil may be operable to at least partially surround and abut the body of the child located on the pediatric RF coil assembly, while the head coil may at least partially surround and abut the head of the child located on the pediatric RF coil assembly. In order to optimize workflow, the child may be positioned on the pediatric RF coil assembly in a first room and moved to a second room including an MRI system after the child is brought to sleep or sedated in the first room. The pediatric RF coil assembly and the child may be moved to the second room using a handle rotatably attached to the pediatric RF coil assembly, and may be positioned on a patient table of the MRI system when the imaging process is to begin.

    摘要： An adapter for a local coil for a magnetic resonance tomography device is provided. The adapter is placeable on a patient support for the magnetic resonance tomography device. The adapter includes an adapter upper part that is removably connectable to the local coil. The adapter also includes an adapter lower part that is removably connectable to the patient support. The adapter also includes a tilt device, by which the adapter upper part is movable relative to the adapter lower part.

    摘要： A radio-frequency coil arrangement has a number of conductor traces forming basic coils and with capacitors interconnected in the conductor traces. Conductor traces of various basic coils intersect at node points. At least one switching arrangement for selective, reversible connection of the conductor traces to form different coil geometries is provided at least some of the node points.
