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 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 object's surface and show changes in B₁ inhomogeneity. We herein assess the gel's effect using a plastic-bottle phantom on a 3T MR system.
