METHOD AND APPARATUS FOR RECONSTRUCTION OF MAGNETIC RESONANCE IMAGE DATA FOR MULTIPLE CHEMICAL SUBSTANCES IN MULTI-ECHO IMAGING

摘要

In a method and apparatus for the reconstruction of image data for at least two different chemical substance types, the reconstruction relates to a defined region of an examination object and is based on raw data acquired from the defined region at different echo times by a magnetic resonance scan. The reconstruction is implemented using a target function that includes a regularization term that correlates image data of the different echo times. A method for ascertaining image data for at least two different chemical substance types in a defined region of an examination object by an imaging magnetic resonance scan can also be implemented.

1. A method for reconstructing image data for at least two chemical substance types in a defined region of an examination object, comprising:
providing a processor with raw magnetic resonance data acquired from a defined region in an examination object at different echo times in a magnetic resonance scan, said defined region comprising at least two different chemical substance types; in said computer, executing a reconstruction algorithm to reconstruct image data from said raw data, using a target function, comprising a regularization term, that correlates image data of the different echo times, in order to produce a reconstructed image of the region in which at least one of said two different chemical substance types is represented; and making the reconstructed image available from the computer in electronic form.
