  • Publication number: 20150355302
    Abstract: A simultaneous MR imaging method is described in which different types of atom are simultaneously excited and read out. First a multi-resonant RF excitation pulse is transmitted including a plurality of sub-signals assigned to different types of atom and having different frequency ranges. Simultaneously or in a synchronized manner, a gradient scheme common to the different types of atom is transmitted with which an unambiguous spatial assignment of received signals can be performed. In the subsequent readout process, an echo signal is received including different individual echoes of different types of atom. The received echo signal is separated into individual signals. Finally, image data is reconstructed from raw data obtained from the separated individual signals. Also described is an apparatus with which the above described method can be carried out.

  • Patent number: 9116212
    Abstract: 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.
