Problems solved by technology

[0003] However, the continuous improvement of image quality is accompanied by an increase in the number of images to be judged
This results in an increasing amount of time required to review images for each patient
As the number of images to be judged increases, the risk of ignoring lesions in a large amount of information also increases

Embodiment Construction

[0034]In the past it has supported physicians in diagnosis by offering them the possibility to generate a vessel centerline. For the establishment of the vessel centerline, the diagnostician must place two or more click points in the vessel being diagnosed. A blood vessel centerline is automatically generated based on the click point. CPR can be provided to radiologists as an overview of the state of individual vessels from the vessel centerline. A solution for the fully automatic generation of a vessel centerline has already been presented in the applicant's unpublished patent application with the document number DE 10 2009 032 257.4.

[0035] According to the invention, the modeling of anatomical knowledge from a large number of vascular trees and the extraction of vascular trees from existing datasets is based on the following three components:

[0036] -Graph model: Consists of logos and vascular connections

[0037] - Statistical vessel model: includes anatomical knowl...

Abstract

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.

Description

technical field [0001] The invention relates to a method for automatic vectorization of the course of a vessel tree and at least one feature thereof on the basis of a tomographic image representation of a patient under examination. Furthermore, the invention relates to a computer system for image analysis, in particular a computer system of a tomography system with a scanner, having a memory for a computer program for carrying out the method described above. Background technique [0002] In the field of imaging methods in medicine it is generally known to extract tomographic image information of a patient in order to obtain therefrom knowledge about the physiological situation of the patient under examination and to provide this knowledge to a physician for diagnostic purposes. For example, in CT angiography, after administration of a contrast agent, a 3D data record of the vascular system is generated which enables a doctor to diagnose deformations of blood vessels, such as...
