Claim Text:
1. A respiratory motion determination apparatus for determining respiratory motion of a living being, the respiratory motion determination apparatus comprising: a raw data providing unit for providing raw data assigned to different times, wherein the raw data are indicative of a structure, which is influenced by cardiac motion and by respiratory motion of the living being and which is a structure of the living being, wherein the raw data are usable for reconstructing an image of the structure, a reconstruction unit for reconstructing intermediate images of the structure from the provided raw data, a structure detection unit for detecting the structure in the reconstructed intermediate images, a respiratory motion determination unit for determining the respiratory motion of the living being based on the structure detected in the reconstructed intermediate images, wherein the raw data providing unit is adapted to provide nuclear raw data as the raw data and the respiratory motion determination unit is adapted to determine the positions of the structure in the reconstructed intermediate images as the respiratory motion of the living being and to determine for each reconstructed intermediate image the respective respiratory phase of the living being depending on the positions of the structure detected in the reconstructed intermediate images.
