摘要： A method of creating a model of an organ, includes creating a shape model, including a blood vessel structure, of the organ based on three-dimensional (3D) images of the organ, and compartmentalizing the shape model into areas based on an influence of a blood vessel tree with respect to a deformation of the shape model, the blood vessel tree indicating the blood vessel structure. The method further includes deforming the blood vessel structure of the shape model to fit a blood vessel structure of a two-dimensional (2D) image of the organ, and creating the model of the organ based on the deformed blood vessel structure and the areas.
