概要

• 論文の詳細を見る

• We developed an original dielectric-equivalent gel (Japanese Patent Application ID: P2004-236876A, February 6, 2003) pad that could improve inhomogeneous images caused primarily by B1 homogeneity on a high-tesla magnetic resonance (MR) system. Made easily from various ingredients, our gel could reduce interference from radiofrequency waves at an objects surface and show changes in B1 inhomogeneity. We herein assess the gels effect using a plastic-bottle phantom on a 3T MR system.
