Abstract

Ensuring optimal homogeneity of the static magnetic field (B0) is critically important for significantly enhancing the image quality, spectral resolution, and overall diagnostic accuracy of magnetic resonance imaging (MRI) and magnetic resonance spectroscopy/spectroscopic imaging (MRS/MRSI), especially at high and ultra-high field strengths. Achieving this goal relies on the deployment of advanced, higher-order shim hardware, which is indispensable for effective and precise B0 shimming.
