    摘要: A method is proposed for calibrating an instrument location facility with an imaging apparatus. The instrument location apparatus and the imaging apparatus are synchronized temporally with one another. According to such synchronization at least three points of the position of a medical instrument relative to a tracking coordinate system of the instrument location apparatus and/or relative to an image coordinate system of the imaging apparatus are measured simultaneously both by the instrument location apparatus and by the imaging apparatus. The instrument and/or the imaging apparatus are moved relative to one another between the measurements. The measured points parameterize a predetermined transformation rule for mapping the tracking coordinate system onto the image coordinate system.

    摘要: An intuitive user interface is provided for endoscopic view visualization. The user interface may permit individual or simultaneous navigation through images displayed in an endoscopic view window, a three dimensional overview window, and a multi-planar reformatted window. An operation performed directly on one of the windows may commence the navigation. The endoscopic view window may be divided into a plurality of sub-regions, each sub-region having a corresponding navigation function. The endoscopic view window and the three dimensional overview window may have corresponding icons related to a single location in corresponding images being displayed. The corresponding icons may be color coded to facilitate intuitive alignment of the corresponding images displayed in the different windows. The three dimensional overview window may have a geometric icon to facilitate intuitive alignment of the corresponding images. The multi-planar reformatted window may permit spherical navigation through the images displayed.

    摘要: The invention relates to a device for merging a 2D radioscopy image with an image obtained from a 3D image data record, having a memory unit that stores the 2D radioscopy image and the 3D image data record, a segmentation unit that segments an inner surface of a hollow organ from the 3D image data record, a registration unit that registers the 2D radioscopy image with the 3D image data record, a back-projection unit that back-projects the pixels of the 2D radioscopy image onto the segmented surface, taking account of the projection geometry of the 2D radioscopy image and the registration, and an image merger unit that generates a virtual endoscopy view of the surface from the segmented surface using the back-projected pixels. The device primarily allows 2D radioscopy images to be superimposed during interventional procedures with a fly display of the interior of an interesting organ.
