摘要： A data set describing a vascular system in three dimensions is pre-specified to a computer. A section of the vascular system is selected. With the aid of the data set describing the vascular system in three dimensions, the computer calculates a length of the selected section. A sequence of images of the vascular system is pre-specified to the computer, wherein a time is assigned to each image. One image respectively of the sequence is defined as a start image and as a stop image. With the aid of the length of the selected section and the times assigned to the start image and the stop image, the computer determines a velocity and outputs the velocity together with the selected section to a user. The operating method can be integrated in particular into the clinical workflow.

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： 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： 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： A sequence of groups of projection images shows an object under examination comprising a vascular system and its environment. A computer determines a 2-dimensional evaluation image having a plurality of pixels based on combination images determined from the projection images of a group. The combination images have a plurality of pixels with pixel values. The sequence of the combination images shows the time characteristic of the distribution of a contrast medium in the object. The pixels of the evaluation image correspond to those of the projection images. The computer assigns each pixel, at least in a part area of the evaluation image, a type that is characteristic of whether the respective pixel corresponds to a vessel of the vascular system, a perfusion area or a background. It performs the assignment of the type on the basis of the time characteristic of the pixel values of the combination images.

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.
