    摘要: There is described an analysis method for at least one image data record of an examination object, wherein each image data record features a multiplicity of image data elements. A position in a multidimensional space is assigned to each image data element. Each image data element features an image data value. The image data values of positionally corresponding image data elements of the image data records are specified by means of at least essentially positionally identical regions of the examination object. A computer automatically divides the image data records into empty regions and signal regions, applying an overall assignment rule which is based on the image data values of the image data elements of a plurality of image data records, such that each image data element of each image data record is assigned to either its empty region or its signal region. For each image data record, the computer automatically determines a closed outline which fully contains the signal region of the relevant image data record and, on the basis of the closed outline of the relevant image data record, determines an analysis region such that a further analysis of the relevant image data record can be restricted to its analysis region.

    摘要: In a computerized workflow method for stent planning and conducting a stenting procedure, characteristics of a lesion to be stented are determined from a 3D planning image of the region and selection of an actual stent for stenting the lesion is made with computer-assisted analysis of the lesion based on the characteristics. A virtual stent is electronically generated based on the actual stent, and, using the virtual stent, a best position for the actual stent, for effectively stenting the lesion, is determined. A real time 2D image of the lesion-containing region is displayed during the stenting procedure, with the virtual stent included therein at the aforementioned best position. A physician manually guides the actual stent relative to the lesion during the stenting procedure until the position of the actual stent, as seen in the displayed real time 2D image, coincides with the virtual stent in that image.

    摘要: An optical coherence tomography system includes a catheter in which is arranged a plurality of light conducting fibers. It further includes a plurality of optical units. Light from the proximal end to the distal end and signals from the distal end to the proximal end can be transmitted simultaneously in different fibers. Time is saved through the simultaneous signal processing of signals from different fibers. That is advantageous particularly in the imaging, by means of coherence tomography, of blood vessels that have to be occluded for said imaging.

    摘要: The invention relates to an arrangement for assisting a percutaneous intervention, comprising an imaging system for tomographic imaging, a robot registered therewith and devices for capturing movements of the patient. A processing unit registers a 4D image dataset recorded before the intervention with a 2D or 3D image dataset of the patient which was recorded immediately before the intervention by the imaging system at a defined respiratory position. From this image data, the access path is transmitted to the robot as a function of the movements captured during recording the 4D image dataset and registration, said robot in turn, depending on the instantaneous movement data, holding the instrument on a predetermined target path and preventing the instrument from being advanced by the person if and as long as the instantaneous movement data does not match the previously recorded movement data. The arrangement reduces the risk of puncture errors.

    摘要: A recording arrangement of an x-ray system comprises an x-ray source and an x-ray detector. Adjustment parameters can be manually supplied to the recording arrangement by an operator of the x-ray system, so that the x-ray source emits x-rays according to the manually given adjustment parameters and the x-ray detector accordingly acquires a sequence of images of an object. The manually supplied adjustment parameters can be automatically acquired by an acquisition device and stored in a remanent memory at least temporarily assigned to the acquisition device and remain stored after the completion of the acquisition of the sequence independently of a further operation of the x-ray system. The stored adjustment parameters can be retrieved from the remanent memory by the operator and supplied again to the recording arrangement so that a further sequence of images can be acquired according to the retrieved adjustment parameters.

    摘要: In the English translation document, please replace the abstract with the following: 2-D projection images show the temporal profile of the distribution of a contrast medium in an examination object, which contains a vascular system and its surroundings. Each projection image comprises pixels with pixel values. The pixel values of pixels corresponding to one another in the projection images are defined by at least essentially locationally identical areas of the examination object. A computer assigns a uniform 2-D evaluation core that is uniform for all corresponding pixels at least in a sub-area of pixels corresponding to one another in the projection images that is uniform for the projection images. The computer defines at least one characteristic value for each pixel within each projection image based on the evaluation core assigned to the pixel and assigns it to the relevant pixel. Based on the temporal profile of the characteristic values, the computer defines parameters of at least one function of time, so that any deviation between the function parameterized with the parameters and the temporal profile of the characteristic values is minimized. Based on the parameters the computer defines a type and/or an extent and assigns them to a pixel of a 2-D evaluation image corresponding to the pixels of the projection images. The type indicates whether the respective pixel of the evaluation image corresponds to a vessel of the vascular system, a perfused part or a non-perfused part of the surroundings of a vessel of the vascular system. The extent is characteristic of perfusion. The computer outputs at least the sub-area of the evaluation image to a user via a display device.
