摘要： The invention relates to a method for “truncation correction” in an x-ray system, i.e. a correction method during the reconstruction of projection images of an object recorded from different projection angles, if parts of the object do not lie in the field of view of each projection image. The surface of the object is thereby optically detected and used during the reconstruction of projection images to supplement the missing image data.

摘要： Two 3D image data records are obtained mutually independently comprising healthy myocardium, myocardium having a reduced blood supply, and the necrotic myocardium. The image data records are combined to produce an overall image data record after registration, and 2D image representations are produced from the overall image data record in which the necrotic parts of the myocardium are shown emphasized, with simultaneously showing the endocardium or the healthy parts of the myocardium and parts having a reduced blood supply. The overall image data record can be used afterwards. For example, further registering step is carried out using images obtained during an intervention on the myocardium. The further registering step enables the necrotic parts of the myocardium to be assigned to the patient's situation. That can extend as far as catheters being moved automatically up to a boundary of the necrotic myocardium.

摘要： A method for providing measuring data for the precise local positioning of an ablation catheter comprises the recording of electrophysiological potential curves in a plurality of positions of the ablation catheter with regard to a potential measurement on a reference catheter. An x-ray image is recorded in each of the positions and the position of the ablation catheter in each instance on the x-ray image is characterized by a marker. The electrophysiological potential curves are coupled in a data-related manner with the markers. When a marker on the screen displaying the x-ray image is clicked on, the associated electrophysiological potential curves appear highlighted on another screen, if necessary in color or with increased brightness. Conversely, the x-ray image with the marker is queried, i.e. displayed and the marker highlighted when the potential curve is activated on a screen displaying the potential curve.

摘要： The present invention relates to a method for determining the position of an instrument in a structure of an object with an x-ray system, in which a 3D image data record is provided for at least one area of the object relevant for determining the position, the x-ray system is registered with the 3D image data record, after the introduction of the instrument into the structure at least one 2D x-ray image of the relevant area is recorded from at least one direction of projection with a known projection geometry with the x-ray system and a 2D position of a first location of the instrument is recorded in the 2D x-ray image. In the method a projection line in accordance with the known projection geometry is placed through the 3D image data record at the 2D position and a 3D position of the first location of the instrument in the 3D image data record is determined from an intersection of the projection line with the structure. The method enables the 3D position to be determined with a simple monoplanar x-ray system.

摘要： In a method for producing an image sequence on the basis of two volume datasets that were acquired at different points in time, a first set of deformation vectors is determined that maps image contents of the first volume dataset onto image contents of the second volume datasets, subsequently a second set of deformation vectors is determined that maps image contents of the second volume dataset onto image contents of the first volume dataset. Subsequently, sets of intermediate volume datasets are produced using attenuated deformation vectors with deformation factors Ai and Bi. Dependent on the size of the deformation factors, the image information of the individual intermediate volume datasets are shifted to different degrees in relationship to the corresponding volume dataset. Subsequently, a set of dissolve volume datasets is produced and displayed as an image sequence.

摘要： The present invention relates to a method to compensate for patient motion in series recordings in medical imaging, in which a plurality of images of an examination area of a patient (17) are recorded at time intervals with an imaging system (1) and related to each other. The invention also relates to an imaging system (1) for implementing the method. With the method, before the start of the series recordings a 3D image data set is recorded by a 3D recording of the examination area, which establishes a reference system. A first spatial position of the examination area in the reference system is then either obtained by recording a first image of the series recordings and registering it with the 3D image data set or by calculating it from a known calibration of the imaging system (1). Each further image of the series recordings is registered immediately after recording with the 3D image data set, to obtain the current spatial position of the examination area in the reference system. Finally a difference in respect of the first spatial position is determined and at least some of the difference is compensated for at least approximately by changing geometric relationships of the imaging system (1) in temporal proximity to registration. The method allows patient motion to be compensated for without interaction by the user of the imaging system.
