摘要:
The invention relates to a motion determination device for determining the motion of an object. The motion determination device comprises a magnetic resonance (MR) information providing unit (2, 5) for providing an MR image of the object (6) and for providing non-image MR data of the object which have been acquired at different acquisition times, and a motion determination unit (9) for determining a motion field, which describes the motion of the object (6), depending on the provided non-image MR data acquired at the different acquisition times and the provided MR image. Since the non-image MR data, which are preferentially k-space data, are directly used for determining the motion field, i.e. without an intermediate reconstruction of MR images based on the non-image MR data, the motion field can be determined with a very high temporal resolution.
