Abstract: To intraoperatively generate an updated volume data set in which a image information of biological tissue is volume data set representing reconstructed from a series of n 2D biological tissue x-ray projections, one version, in intraoperatively acquired m 2D biological tissue x-ray projections the biological tissue 2D contour is segmented and this is back-projected in the reconstructed volume data set. In another version, in the volume data set the biological tissue 3D contour is segmented and this is projected in intraoperatively acquired m biological tissue 2D x-ray projections. The 3D contour is visually repositioned by projection in the m 2D x-ray projections in the volume data set, until its projection is substantially congruent with the biological tissue image information in the respective 2D x-ray projections. In both versions, a volume data set updated around the intraoperatively determined biological tissue 3D contour is generated.

Abstract: In a method and apparatus for catheter navigation in three-dimensional vascular tree exposures, particularly for intercranial application, the catheter position is detected and mixed into the 3D image of the pre-operatively scanned vascular tree reconstructed in a navigation computer and an imaging (registering) of the 3D patient coordination system ensues on the 3D image coordination system prior to the intervention using a number of markers placed on the patient's body, the position of these markers being registered by the catheter. The markers of a C-arm x-ray device for 3D angiography are detected in at least two 2D projection images, from which the 3D angiogram is calculated, and are projected back on to the imaged subject in the navigation computer and are brought into relation to the marker coordinates in the patient coordinate system, using projection matrices applied to the respective 2D projection images, these matrices already having been determined for the reconstruction of the 3D volume set of the vascular tree.

Abstract: A method and a device for obtaining a volume data set of a mobile tissue or organ of a patient by a C-arm X-ray device are provided. An electromagnetic sensor of a position detection system is arranged indirectly on the tissue or organ. The X-ray device obtains a plurality of X-ray projections from the tissue or organ from various projection directions. A first method consists of reconstructing a volume data set from the X-ray projections, in which the electromagnetic sensor adopts a position characterizing a displacement phase of the tissue or organ. A second method consists of reconstructing a volume data set from the X-ray projections captured when the electromagnetic sensor was located in a position characterizing a displacement phase of the tissue or organ. A third method does not capture an X-ray projection for the reconstruction if the electromagnetic sensor is located in a position characterizing a displacement phase.

Abstract: The invention relates to a method and a device for the combined representation of a series of 2D fluoroscopic images of the beating heart with a static 3D image data set of the same heart. The fluoroscopic images are registered with the 3D image data set and from this a 2D pseudo-projection on to the image plane of each fluoroscopic image generated in each case. This is then represented with the associated fluoroscopic image overlaid. The method is characterized in that the pseudo-projection is represented differently in each case or is not represented depending on the interval of the cardiac phase of the currently represented fluoroscopic image relative to the cardiac phase of the 3D image data set.

Abstract: A device and a method for controlling ablation energy for performing an electrophysiological catheter application are provided. Measured parameters that are characteristic for guidance of a catheter are received by a communication module. The characteristic parameter values are compared with at least one predefined threshold value by a control module. The control module generates control data for guidance of the catheter as a function of the result of the comparison. The control data is output to at least one control station by output interfaces for controlling the guidance of the catheter for the purpose of adjusting the ablation energy of the catheter.
