Description	The magnetic resonance (MR) imaging techniques of tomography and spectroscopy are exploited in many applications. The quality of dynamic behavior of gradient magnetic fields is one of the important properties of devices exploiting the phenomenon of magnetic resonance (MR) for imaging or diffusion measurement. A necessary precondition for the facilitation of MR instruments proper functioning consists in the maintenance of a high degree of homogeneity of the fundamental and gradient magnetic fields. Gradient changes induce eddy currents in the surrounding conducting arrangement, thus potentially causing image artifacts, localization errors, and signal distortion. While the use of actively shielded gradients has greatly reduced the magnitude of eddy currents, significant distortion often remains, mainly in the short time interval after the gradient is switched off. Residual eddy currents may require further reduction. This is frequently achieved by pre-emphasis correction in the relevant gradient channel The magnetic resonance (MR) imaging techniques of tomography and spectroscopy are exploited in many applications.
