Progressive model-based adaptation

A method (600) of adapting a deformable model comprising a plurality of model elements to an object of interest in an image data set, said method comprising:

• a selecting step (640) for selecting at least one image-driven model element from the plurality of model elements;
• and
• an adapting step (650) for adapting the deformable model on the basis of optimizing a model energy of the deformable model, said model energy comprising an internal energy of the plurality of model elements and an external energy of the at least one image-driven model element, thereby adapting the deformable model.

A computer program product to be loaded by a computer arrangement, comprising instructions for adapting a deformable model comprising a plurality of model elements to an object of interest in an image data set, the computer arrangement comprising a processing unit and a memory, the computer program product, after being loaded, providing said processing unit with the capability to carry out the following tasks:

• selecting at least one image-driven model element from the plurality of model elements;
• and
• adapting the deformable model on the basis of optimizing a model energy of the deformable model, said model energy comprising an internal energy of the plurality of model elements and an external energy of the at least one image-driven model element, thereby adapting the deformable model.
