A Study on Aliasing Artifact Shielding Materials using Aluminum Material in Magnetic Resonance Imaging

In order to remove the aliasing artifact that occurs during magnetic resonance imaging, a shield was fabricated using aluminum, which is inexpensive and easily available in the vicinity, among materials that are not affected by magnetic fields, and its usefulness was evaluated. In the experiment using Phantom, it was confirmed that perfect shielding was achieved and no aliasing artifacts appeared. In addition, it was confirmed that the aliasing artifact was removed in the quantitative signal strength evaluation, and it was confirmed that the aliasing artifact was removed and the scan time was not increased in the ghost signal percentage evaluation, confirming the usefulness as a shielding body.
