In a magnetic resonance imaging apparatus, a sensor (120, 122, 124, 126,
130) measures a displacement of a feature of interest. A magnetic
resonance imaging scanner (10) acquires radial readout lines of magnetic
resonance imaging data. A reconstruction processor (58) reconstructs the
acquired readout lines into reconstructed image data A coordinating
processor (134, 140) coordinates a direction of a radial readout line
with the determined displacement. The coordinating processor (134, 140)
biases at least one of the magnetic resonance imaging scanner (10) and
the reconstruction processor (58) toward a selected relationship between
readout magnetic field gradient direction and the determined displacement
of the feature of interest.
