title: Reduction of a high-field dielectric artifact with homemade gel.
abstract: 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 B(1) homogeneity on a high-tesla magnetic resonance (MR) system. Made easily from various ingredients, our gel could reduce interference from radiofrequency waves at an object's surface and show changes in B(1) inhomogeneity. We herein assess the gel's effect using a plastic-bottle phantom on a 3T MR system.
