## Abstract The quality of volumeβlocalized magnetic resonance spectroscopy is affected by eddy currents caused by gradient switching. Eddy currents can be reduced with improved gradient systems; however, it has been suggested that the distortion due to eddy currents can be compensated for during p
Lineshape distortion due to residual eddy currents and magnetic field inhomogeneities are often present in short echo time 1 H spectroscopic data. Lineshape correction methods such as QUALITY deconvolution and eddy current correction (ECC), which use a separate reference spectrum for lineshape corre
## Abstract A programmable preemphasis system has been developed for eddyβcurrent compensation in gradient sets with or without active screening. Preemphasis parameters are nonvolatile but can be changed rapidly when working with interchangeable gradient sets. The design allows easy retrofit to exi
