Abstract
A programmable preemphasis system has been developed for eddy-current compensation In gradient sets with or without active screening. Preemp hasis parameters are nonvolatile but can be changed rapidly when worki ng with interchangeable gradient sets. The design allows easy retrofit to existing systems. A method for setting the preemphasis is presente d, together with specimen results.
