摘要： 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.

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.

摘要： A method and a device for visually assisting a catheter application on the heart of a patient using an image of the patient obtained by a C-arm X-ray device and using electroanatomical mapping data of the patient obtained by an electromagnetic position detection system and mapping system. The C-arm X-ray device and the electromagnetic position detection system and mapping system are calibrated in relation to each other, by determining a co-ordinate transformation between a co-ordinate system assigned to the C-arm x-ray device and/or a co-ordinate system assigned to the image generated by the C-arm X-ray device and a co-ordinate system assigned to the electromagnetic position detection system and mapping system. The position of the patient is determined during the detection of the image and/or during the detection of the electroanatomic mapping-data and is at least indirectly assigned to the image and/or the electroanatomic mapping-data.

摘要： 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.

摘要： 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.

摘要： The invention relates to a method for locating a medical instrument (2a, 2b) at least partly inserted into an object under examination (U), there being acquired (11, 13) images of the object under examination (U) which capture the medical instrument (2a, 2b). A method which requires as little user interaction as possible can be provided by virtue of the fact that an image is acquired under first acquisition conditions and a substantially identical image is acquired under second acquisition conditions (11, 13), and the fact that the medical instrument (2a, 2b) is located from a subtraction (14) of image data sets of first and second acquisition conditions.
