In a method for selective presentation of a movement of the lung, magnetic
resonance images (MR images) of the lung are acquired in a temporal
progression, i.e. MR images of the lung are acquired over multiple
breathing cycles. The acquired MR images are registered with regard to a
reference position and the signal curve over time is determined in the
acquired MR images. The frequency spectrum of the determined signal
curves is then determined, such as by a Fourier transformation. A
specific frequency spectrum is filtered with a frequency band filter,
wherein the frequency range of the frequency band filter is adapted to
the movement to be shown. The filtered frequency spectrum is transformed
back into a filtered signal curve of the MR images, and the magnetic
resonance images obtained via this back-transformation are displayed in
the temporal progression with the filtered signal curve. A computer
readable medium, an image processing unit and a magnetic resonance
apparatus implement such a method.
