1. A method of lung lobe segmentation comprising the steps of:
- providing of three dimensional first image data of a lung,performing segmentation of the first image data with respect to a tubular structure located within the lung to identify first voxels of the first image data belonging to the tubular structure and to identify second voxels of the first image data which do not belong to the tubular structure,performing an image transformation on the first image data being expressive of a degree of association between the identified first and the second voxels to provide second image data,performing a weighted combination of the first image data and the second image data to provide third image data,performing a lobe segmentation based on the third image data, andobtaining an output of the lobe segmentation indicative of the lobes of the lung.

Abstract
A method of lung lobe segmentation having the steps of: providing of three dimensional first image data of a lung; segmentation of a tubular structure to identify first voxels of the first image data belonging to the tubular structure and to identify second voxels of the first image data which do not belong to the tubular structure; determining a distance measure for each one of the second voxels, by determining a minimum distance between each one of the second voxels to one of the first voxels to provide second image data; and performing a lobe segmentation based on the second image data.

13. A computer readable medium containing program instructions for performing lung lobe segmentation;
- performing segmentation of a three dimensional first image data of a lung with respect to a tubular structure located within the lung to identify first voxels of the first image data belonging to the tubular structure and to identify second voxels of the first image data which do not belong to the tubular structure;
performing an image transformation on the first image data being expressive of a degree of association between the identified first and the second voxels to provide second image data;
