Method for Generating a Quantitative Parameter Map from MR Data, Associated Computer Program and Storage Medium, and Magnetic Resonance System

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

This patent describes a method for creating a quantitative parameter map from magnetic resonance (MR) data using a signal model. The process involves using a multi-echo MR sequence, where the phase evolution of each echo is mapped and modeled consistently across defined image regions (pixel fields), which helps improve the stability and accuracy of the parameter map calculation.

Patent Abstract

Techniques are disclosed for generating a quantitative parameter map from MR data. A specified signal model is adjusted to measured MR data. The signal model contains a time-dependent phase evolution map that specifies a respective separate phase evolution for each echo in a multi-echo sequence used to generate the MR data. Provision is also made for an image region that is to be represented to be divided up into a plurality of pixel fields, which include a plurality of pixels in each case. For all these pixel fields, at least the phase evolution for each echo is assumed to be equal for all the pixels in the respective pixel field, so as to achieve stability of the adjustment of the signal model to the MR data.
