Multi-Point Magnetic Resonance Imaging

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes an advanced method for multi-point magnetic resonance imaging (MRI). It processes complex MRI data obtained at multiple echo times from various spin species in the scanned area, applying optimization techniques to improve image accuracy by correcting for field inhomogeneities and other artifacts. The method ultimately produces MRI images with enhanced contrast specific to different tissue or material types.

Patent Abstract

A method for multi-point magnetic resonance imaging including: receiving measured magnetic resonance data, which maps the magnetizations of a number of spin species in a measuring range with a number of echo times; carrying out an optimization for determining fitted magnetic resonance data on the basis of the measured magnetic resonance data, wherein an optimization function of the optimization implements a penalty for a higher rank of a matrix representing the fitted magnetic resonance data and a correction term for the localized evolution of a phase of the measured magnetic resonance data by means of field inhomogeneities or by means of a counterrotation of gradient fields with the number of echo times; and applying a spectral model to the fitted magnetic resonance data to determine magnetic resonance images with contrasts which correspond to the number of spin species.
