Classification: CPC G | IPC G

Claim 13:
14. A non-transitory computer readable storage medium program comprising instructions which, when running on at least one computer, causes the at least one computer to perform the method steps of
determining distributions of corrections for correcting a segmentation of medical image data, which includes:
acquiring initial segmented patient image data which describes an initial segmentation of digital medical images of an anatomical body part of a first plurality of patients;
acquiring segmentation correction data which describes a correction of the initial segmentation for each patient of the first plurality of patients;
acquiring atlas data which describes an image-based model of the anatomical body part;
determining correction transformation data based on the segmentation correction data and the atlas data, wherein the correction transformation data describes a transformation for transforming the corrections into a reference system used for describing positions in the image-based model;
determining transformed correction data based on the segmentation correction data and the correction transformation data by applying the transformation to the corrections to determine transformed corrections;
determining combined correction data is determined based on the transformed correction data, wherein the combined correction data describes the results of a statistical analysis of the corrections;

wherein a computer-implemented method of determining corrections for correcting the segmentation of medical image data further includes:
acquiring segmented individual patient image data which describes a segmentation of the anatomical body part of the patient in a digital individual medical image;
determining correction re-transformation data based on the atlas data and the individual patient image data, wherein the correction re-transformation data describes a transformation for transforming the results of the statistical analysis of the corrections into a reference system used for describing positions in the digital individual medical image;
determining re-transformed correction data based on the combined correction data and the correction re-transformation data; and
determining corrected segmented patient image data based on the individual patient image data and the re-transformed correction data, wherein the corrected segmented patient image data describes a result of applying the corrections to the segmentation of the anatomical body part of the patient in the digital individual medical image.
