Gradient nonlinearity calibration and correction for a compact, asymmetric magnetic resonance imaging gradient system
Due to engineering limitations, the spatial encoding gradient fields in conventional magnetic resonance imaging cannot be perfectly linear and always contain higher-order, nonlinear components. If ignored during image reconstruction, gradient nonlinearity (GNL) manifests as image geometric distortio...
