Abstract
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.
