Method for creating a production model for a patient-specific medical object
A method is disclosed for creating a production model for a patient-specific medical object. Image data relating to a body region are segmented into regions, each region corresponding with structures of different tissue. By way of the regions that correspond with the structures, a number of shape features is determined for the medical object. The shape features are compared with shape data relating to a plurality of stored object data sets. On the basis of the comparison of the shape features with the shape data, a prototype of the medical object is specified. The prototype of the medical object is defined as a production model. The production model is stored on a data carrier and/or output via an interface.
