    Abstract: An operating method for a polyplanar imaging system for time-resolved imaging of an object is provided. First and second data records are recorded at a fan angle β from different angular positions by a first and second imaging planes arranged at an offset angle γ relative to each other and swiveled through an angle of at least φ=180°+β. A third data record is created by selecting projection images from the first data record beginning from a starting angle α and from the second data record so that the third data record covers an angular range of at least φ. Three-dimensional images are reconstructed based on the third data record. The starting angle α is varied for continuously creating the third data record until α has attained its final value. The contrast of projection images in the third data record or of three-dimensional images is evaluated.

    Abstract: In a method and system for patient-specific production of a cardiac electrode, such as for use in a biventricular pacing system, a 3D representation of the coronary sinus vessel tree is segmented to indicate the interior surface thereof an a representative line from an opening of the coronary sinus vessel tree to an implantation site for the electrode, and a computerized model of the electrode is generated. 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 the virtual implantation, a 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. If so, an actual electrode conforming to the model is then produced. If not, the model generation and the virtual implantation are iteratively modified until a satisfactory implantation result is achieved according to the virtual implantation.

    Abstract: To visually support a catheter ablation in the heart, three-dimensional image data have been used prior to the intervention. During ablation, the position of the catheter is pinpointed by an orientation system. The orientation system acquires electroanatomical 3D mapping data. the two-dimensional image data is assigned to the 3D mapping data in the correct position and dimensions which is a time-consuming step. The invention makes provision for the orientation system being in a fixed location relative to the X-ray system so that a positionally and dimensionally correct alignment of the X-ray image data set with the 3D mapping data is no longer required. An image or surface based 3D-3D alignment of the three-dimensional data acquired prior to the intervention with the three-dimensional X-ray image data is considerably less time-consuming than alignment thereof with the 3D mapping data and is more reliable because more structures is recognized in the three-dimensional X-ray image data.

    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: In a method for mathematical compensation of a periodic movement of an organ in a first image-generation method used to image said organ, two time series of three-dimensional image data are acquired using gating, one by the first image-generation method and one by the second image-generation method, the image data that have been acquired by the second image-generation method being used to calculate motion fields which are applied for the compensation of the data from the time series which was acquired by the first image-generation method. The compensation encompasses the mathematical inclusion of motion fields and the mapping of the image data to a reference time. All the image data mapped back to the reference time are added together.

    Abstract: 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.
