4D - - image recording velocity profile with a magnetic resonance system

摘要

It is a method (200) for producing 4d - flow images by means of a magnetic resonance system (1) described. In the process, a volumetric flow - data record, wherein the flow in a single direction is encoded. The previous step is then repeated with all the flow directions coding. From the raw data, the coding of the individual flow directions are allocated, phase images (pbd) and magnitudes images (mbd) is calculated. On the basis of the magnitudes images are calculated deformation fields are caculated (dfd). The deformation fields are caculated (dfd) are positioned on the calculated phase images (pbd) applied. Finally, a 4d - flow - velocity field (4d - fgfd) based on a phase difference reconstruction of the corrected phase images (kpbd) is calculated. It is also a device for producing 4d - flow images by means of a magnetic resonance system (1) described.
