ABSTRACT:
In a method for motion tracking an Interventional Instrument with MR Imaging, the interventional instrument is guided on a motion path in a first direction, raw datasets are acquired from nuclear magnetic resonance signals frequency-encoded in the first direction and wavelet-encoded in a second direction perpendicular to said first direction, the raw datasets are updated with a repetition rate only for the wavelet-encodings that are allocated to the region of the motion path, and chronologically-resolved images are acquired from the raw datasets.
