摘要:
A method and a computer system are disclosed for automatic vectorization of the profile of a vessel tree and at least one of its properties on the basis of tomographic images of an examined patient. In at least one embodiment, using previously established location probabilities of landmarks in the vessel tree, there is an automatic determination of a plurality of distinctive landmarks in the current tomographic image data record of the patient, a registration of the current tomographic image data record to the statistical vessel model, an automatic determination of previously unidentified landmarks in the registered tomographic image data record using characteristic identification features of the previously unidentified landmarks from the statistical vessel model and the statistical location probability thereof, and a determination of at least one current vessel model using the identified landmarks and at least one vessel property at and/or between the identified landmarks.
