Abstract
Official abstract text for this publication.
A multi nuclei RF antenna arrangement for use in a multi nuclei MRI system or an MR scanner, for transmitting RF excitation signals (B 1 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 1 H, 14 N, 31 P, 13 C, 23 Na, 39 K, 17 O and hyper polarized gases like 129 Xe 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A multi nuclei RF antenna arrangement comprising: a first antenna for transmitting RF excitation signals for exciting magnetic resonances or for receiving MR relaxation signals from a first species of nuclei having a first gyromagnetic ratio (γ LO ); and a second antenna for transmitting RF excitation signals for exciting magnetic resonances or for receiving MR relaxation signals from a second species of nuclei having a second gyromagnetic ratio (γ H…
