RECONSTRUCTING MAGNETIC RESONANCE IMAGES WITH DIFFERENT CONTRASTS

摘要

A method and a device for reconstructing magnetic resonance images with different contrasts are provided. According to an example of the method, after collecting magnetic resonance signal data recorded in k-space of N contrasts by N number of magnetic scans, a first image for each of the contrasts may be obtained by performing image reconstruction according to the magnetic resonance signal data corresponding to the contrast; an association coefficient of each of the contrasts may be determined according to the first images for the N contrasts; and a second image shared with the N contrasts may be obtained by performing image reconstruction based on the magnetic resonance signal data of the N contrasts and the association coefficient of each of the N contrasts. In this way, a reconstructed image for each of the contrast may be obtained by combining the association coefficient of the contrast with the second image.
