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.
