Abstract: A medical image viewing device for navigation in X-ray imaging includes a processor. The processor is configured to perform a 3D-2D registration of a preoperative three-dimensional volume based on geometry parameters of an image data provider, which provides fluoroscopy images of an object of interest and a plurality of structures with interfering motions to be removed, for creating digitally reconstructed radiograph images of these structures for each fluoroscopy image. These are subtracted from the respective fluoroscopy images to generate structure-suppressed fluoroscopy images free from interfering motions. Based on these structure-suppressed fluoroscopy images, an angiographic image sequence is generated performing a motion estimation of the structures.

Abstract: The invention relates to a cavity determination apparatus for determining a cavity within an object, in particular, for determining the location and dimensions of a heart chamber within a person without use of electrode contact information. A bendable segment of an introduction element is arranged within the cavity in different arrangements, wherein curves defined by the bendable segment in the different arrangements are determined by a curve determination unit. A cavity reconstruction unit reconstructs the cavity based on the determined curves. Thus, not only single locations within the cavity are acquired and used for reconstructing the cavity, but larger curves. A considerable amount of spatial information can therefore be acquired and used very rapidly. This allows reconstructing the cavity with improved quality in a relatively short time.
