Abstract

A method for preparing the reconstruction of a damaged bone structure using an implant, comprising the following steps which are carried out by a computer (2): a) performing atlas segmentation on a structure dataset which represent the structure to be reconstructed, and determining healthy objects and defective objects within the damaged structure; b) determining a target structure by modelling replacements for the defective objects within the damaged structure; c) selecting an implant on the basis of the target structure, and providing a shape dataset which represents the shape of the implant; d) positioning the selected implant in order to find the optimum implant position; e) determining whether or not the selected implant is suitable, and returning to step c) if the implant is determined to not be suitable; and f) exporting the suitable implant to a medical navigation process.
