  • RF antenna arrangement and method for multi nuclei MR image reconstruction involving parallel MRI
    Patent number: 8929626
    Abstract: A multi nuclei RF antenna arrangement for use in a multi nuclei MRI system or an MR scanner, for transmitting RF excitation signals (B1 field) for exciting nuclear magnetic resonances (NMR), and/or for receiving NMR relaxation signals for multi nuclei MR (magnetic resonance) image reconstruction is disclosed, wherein the RF antenna arrangement is tuned to the Larmor frequencies of at least two different species of nuclei having at least two different gyromagnetic rations like 1H, 14N, 31P, 13C, 23Na, 39K, 17O and hyper polarized gases like 129Xe or other isotopes having a nuclear spin. Further, a method for reconstructing a multi nuclei MR image especially by means of the above RF antenna arrangement is disclosed. The method involves reducing back-folding artifacts of the species having the higher gyromagnetic ration by parallel MRI reconstruction.
