METHOD AND SYSTEM FOR GENERATING MR IMAGES OF A MOVING OBJECT IN ITS ENVIRONMENT

MR images (10, 20) of an object in its environment within a region of interest are generated. The object executes motion including a plurality of moving phases within a period of time. The method includes the steps of: generating a first image (10) of a region of interest from the first dataset (S2); identifying a dynamic region (12) and a static region (14) inside the first image (10) (S3); editing the first image (10) by masking out the dynamic region (14) (S4); performing an inverse Fourier transformation of the edited first image (16) showing the remaining static region (14) (S5); subtracting the inverse Fourier transformation of the edited first image (16) with the remaining static region (14) from a second dataset (S7) pertaining to one of the moving phases of the object (S6); performing a Fourier transformation on the subtracted second dataset (18) (S8); and generating a second image (20) of a reduced region of interest with respect to the region of interest of the first image (10), which reduced region of interest includes the dynamic region (12) (S9).
