摘要： The invention relates to a method for three-dimensional presentation of a moved structure using a tomographic method, in which a plurality of projection images are recorded from different imaging angles between a start angle with a start node point and an end angle with an end node point by an imaging unit during a number of rotation passes, with three-dimensional image data being able to be reconstructed from the projection images, with the projection images being spaced by a path or an edge. For determining the three-dimensional presentation for each angle of projection only those projection images are selected which minimize the sum of the paths or weighted edges between adjacent projection angles for a gating.

摘要： The invention relates to the use of 2D projection images which belong to a specific common heart phase. A 3D image data set can be used to generate a reference projection image for the same projection angle for each of the 2D projection images and a differential image can be derived from the reference projection image and 2D projection image. The differential images are back-projected and combined in one 3D differential image data set and, by using this, a deformed 3D image data set is obtained from the previously recorded 3D image data set. Iterations guarantee that the deformed 3D image data set ensues with the smallest possible distance from the 2D projection images for the existing common heart phase. Finally, a 3D image data set is available for a different heart phase other than the reference heart phase and the possibilities for imaging a patient's heart are extended.

摘要： X-ray images are recorded of a patient's heart and the heartbeat phase is registered as that is done. The heartbeat phases are coarsely divided into intervals and all X-ray images that have been assigned heartbeat phase from the interval are used for reconstructing a 3D image dataset. The movement fields of the other 3D image datasets are then calculated for one of said 3D image datasets. Movement fields are vector fields indicating the movements of similar structures from one local area to the other. A departure is then made from the coarse interval division, and for each heartbeat phase a movement field is interpolated individually or at least for fairly short intervals from the movement fields determined in advance, which field is used for generating a deformed 3D image dataset that has been imaged onto a reference heartbeat phase. The deformed 3D image datasets are then added together.

摘要： In a method and apparatus for fully automatic detection of anomalies in vessel structures, a 3D volume data set of an imaging 3D measurement of the vessel structure is obtained and, for an evaluation device, the vessel structure is detected in the 3D volume data set and subsequently is skeletonized in order to obtain a three-dimensional course of skeletonization paths. Characteristic quantities of the vessel structure are automatically determined along the skeletonization paths as features that are significant for an anomaly to be detected, in order obtain one or more feature series. The determined feature series are classified by non-linear imaging and comparison with reference feature series that have been determined for different classes of known vessel structures that contain different anomalies and known vessel structures without anomalies. Anomalies corresponding to the classification thus are identified.
