Title:
ARTEFACT REDUCTION IN MAGNETIC RESONANCE IMAGING
Document Type and Number:
WIPO Patent Application WO/2021/081309
Kind Code:
A3
Abstract:
A method of operating a low-field magnetic resonance imaging (MRI) system, the method comprising: obtaining an initial set of k-space phase-encoding coordinates; generating a sampling path through at least some of the k-space phase-encoding coordinates in the initial set to mitigate impact of eddy currents on operation of the low-field MRI system; and operating the low-field MRI system using a pulse sequence in accordance with the sampling path to obtain spatial frequency data for generating one or more magnetic resonance (MR) images of a subject.
