Abstract
A method for magnetic resonance imaging includes performing a pre-scan using a spin-echo diffusion acquisition with a one-time MRI pulse sequence to measure phase differences between diffusion and non-diffusion acquisitions, which correspond to an estimation of eddy-current-induced phase in a diffusion-prepared sequence; and performing a scan using arbitrary waveform shim currents applied to a shim array during the acquisition, wherein the shim currents are determined from the measured phase differences from the pre-scan to create opposite phase maps to compensate eddy-current or system-imperfection-induced phase differences; wherein the scan and pre-scan are performed using an MRI apparatus with a channel integrated receiver and the shim array.
