A computer implemented data processing method for generating a dynamic anatomic atlas, the dynamic atlas comprising: - static atlas data describing atlas segments; and - dynamic atlas data comprising information on a dynamic property which information is respectively linked to the atlas segments, wherein the information on the dynamic property is obtained from a dynamic digitally reconstructed radiograph, DRR, the method comprising the following steps: - based on the static atlas data a static atlas image of the atlas segments is acquired; - static patient data describing a static patient image of a patient segment is acquired; - dynamic patient data comprising information on a dynamic property is acquired, the information being respectively linked to the patient segment; - the static patient image is matched with the static atlas image; - a corresponding atlas segment corresponding to the patient segment is determined based on the matching; - for generating the dynamic anatomic atlas, the information on the dynamic property linked to the corresponding atlas segment is determined based on the information on the dynamic property linked to the patient segment, characterised in that the information on the dynamic property describes correlations between the dynamic properties of different ones of the atlas segments. - static atlas data describing atlas segments; and - dynamic atlas data comprising information on a dynamic property which information is respectively linked to the atlas segments, wherein the information on the dynamic property is obtained from a dynamic digitally reconstructed radiograph, DRR, the method comprising the following steps: - based on the static atlas data a static atlas image of the atlas segments is acquired; - static patient data describing a static patient image of a patient segment is acquired; - dynamic patient data comprising information on a dynamic property is acquired, the information being respectively linked to the patient segment; - the static patient image is matched with the static atlas image; - a corresponding atlas segment corresponding to the patient segment is determined based on the matching; - for generating the dynamic anatomic atlas, the information on the dynamic property linked to the corresponding atlas segment is determined based on the information on the dynamic property linked to the patient segment, characterised in that the method comprising the following steps: - based on the static atlas data a static atlas image of the atlas segments is acquired; - static patient data describing a static patient image of a patient segment is acquired; - dynamic patient data comprising information on a dynamic property is acquired, the information being respectively linked to the patient segment; - the static patient image is matched with the static atlas image; - a corresponding atlas segment corresponding to the patient segment is determined based on the matching; - for generating the dynamic anatomic atlas, the information on the dynamic property linked to the corresponding atlas segment is determined based on the information on the dynamic property linked to the patient segment, - based on the static atlas data a static atlas image of the atlas segments is acquired; - static patient data describing a static patient image of a patient segment is acquired; - dynamic patient data comprising information on a dynamic property is acquired, the information being respectively linked to the patient segment; - the static patient image is matched with the static atlas image; - a corresponding atlas segment corresponding to the patient segment is determined based on the matching; - for generating the dynamic anatomic atlas, the information on the dynamic property linked to the corresponding atlas segment is determined based on the information on the dynamic property linked to the patient segment, characterised in that the information on the dynamic property describes correlations between the dynamic properties of different ones of the atlas segments.
