1. A method for high precision modeling of a body part, the method comprising the steps of: collecting image data of a body part provided by an imaging system with a first imaging resolution; processing the collected image data of the body part using data representing the imaging behavior of the imaging system and information about the nature of the body part to provide a 3-dimensional description data of the body part, the 3-dimensional description data of the body part having an image resolution better than the first imaging resolution; and processing the 3-dimensional description data of the body part to provide a 3-dimensional parametric description of the body part.
