Imperfect magnetic field gradients in radial k‐space encoding—Quantification, correction, and parameter dependency
Sign Up to like & getrecommendations! Published in 2019 at "Magnetic Resonance in Medicine"
DOI: 10.1002/mrm.27449
Abstract: Sensitivity to imperfections of image‐encoding gradient fields may significantly impair widespread use of radial MR data acquisition. Such imperfections can cause individual echo shifts for each spoke acquired in the k‐space and may produce severe… read more here.

DOI: 10.1063/1.5080241
Abstract: A superhydrophobic surface is non-sticking to aqueous droplets due to minimized solid-liquid contact, but the small contact area also poses challenges to droplet maneuvering. This letter reports a technique using electric field gradients to actuate… read more here.
