1. A method of segmenting an object in a data set, said method comprising:

  • a) initial segmenting of the object, resulting in a first set (N0) of voxels,b) performing an erosion operation on the first set (N0) of voxels resulting in an eroded set (N

    ) of voxels,c) performing a dilation operation on the eroded set (N

    ) of voxels resulting in a dilated set (N+) of voxels, andwherein the erosion operation depends on a variable erosion threshold (Θ



    ) andwherein the dilation operation depends on a variable dilation threshold (Θ

    +).
