For creating the 3D model, the slices that are near the craniotomy surfaces have higher resolutions than the slices far from the surface. For the craniotomy surface, we choose more slices than the other parts because if all parts have the same number of slices, the implementation will be time consuming or the accuracy of the model will be insufficient if the total number of slices is small.
