Abstract: The present invention relates to a method and also an imaging system to compensate for patient motion when recording a series of images in medical imaging, in which a number of images of an area under examination of a patient (17) are recorded at intervals with an imaging system (1) and are related to one another. With the method a localization system (2) is used as the series of images are being recorded to permanently or at a time close to the recording of the individual images, record a momentary spatial location of the area under examination in a reference system permanently linked to the imaging system (1), a first spatial location of the area under examination recorded close to the time of recording of a first image is stored, and a deviation of the images recorded momentarily in each case of the first spatial location is determined and by changing the geometrical circumstances of the imaging system (1) at a time to close the recording of the spatial location and/or through geometrical adaptation of an image content of an image just recorded, is at least approximately commentated for, so that the images show the area under examination in the same position and orientation. The method does not require any time-consuming interaction with the operator and is also suitable for compensating for larger movements of the patient.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
