Abstract: In a method and system for patient-specific production of a cardiac electrode lead, a 3D representation of the coronary sinus vessel tree is segmented to indicate the interior surface thereof and a representative line from an opening of the coronary sinus vessel tree to an implantation site for the electrode lead, and a computerized model of the electrode is generated that includes deformation properties of the mechanical structure of the electrode lead. A computerized virtual implantation of the electrode through the 3D representation of the coronary sinus vessel tree is implemented using the model and the internal surface and the representative line from which determination is made as to whether an electrode conforming to the model can be guided to and implanted at the implantation site in a medically acceptable manner, or whether modification of the electrode lead is necessary.

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: With a method for generating an x-ray image sequence for supporting an intervention on a patient with a catheter or guide wire for instance, automatic recognition of the catheter is carried out with recorded x-ray images using a computer system. The x-ray image recording parameters are changed on the basis of the determined quality of the imaging of the object, with the x-ray device preferably being automatically activated with the changed x-ray image recording parameters, to record x-ray images. The doctor can therefore concentrate on the actual intervention and does not have to worry about operating the x-ray device.

Abstract: A data processing system and method for multi-modal viewing of medical image visualization is described. The system includes an image display device operable to display an on-the-fly (“fly”) visualization of a three dimensional (3D) data set, and a live X-ray image, where the parameters of the “fly” visualization are adjusted so that the “fly” visualization image has a correspondence to the live X-ray image. The method includes recording a three dimensional (3D) data set, and a corresponding live X-ray image; rendering a “fly” visualization of the 3D data set; adjusting the attributes of the “fly” visualization to achieve a correspondence with the live X-ray image; and, simultaneously displaying the “fly” visualization image and the live X-ray image.

Abstract: 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.
