摘要： An x-ray device for recording projection images of a patient features a C-arm on the ends of which an x-ray source and an x-ray detector are accommodated. The x-ray detector is accommodated on the C-arm so that translation movements can be executed with the x-ray detector in relation to the C-arm. This allows the angulation area or the area of the x-ray device with which an image can be recorded to be increased.

摘要： To improve medical imaging with the aid of an intravascular catheter, an area to be examined is irradiated with the infrared light and an assigned scatter light signal is processed to form an image. To do this, OCT imaging with the aid of tissue-permeable light at a wavelength of approximately 1300 nm is combined with OCT imaging with the aid of blood-permeable light at a wavelength of approximately 1800 nm and/or with radio-optic imaging with the aid of an infrared camera (10B) with blood-permeable light at a wavelength of 1800 nm. This combined imaging catheter system opens up new and improved application possibilities in the medical field and the quality of the images received can be improved by the mutual correction of the particular image 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： 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： 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.
