    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： 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 system and method for obtaining perfusion images is disclosed. The system and method includes hardware and software for determining physiological characteristics of a patient and determining imaging parameter values for an imaging modality based on the patient's physiological characteristics. The system also includes a controller operative to receive the imaging parameter values for controlling an X-ray device. The X-ray device is coupled with the controller and acquires projection images of the patient, and outputs the projection images to a perfusion evaluation computer for evaluating the perfusion of an region of interest represented in the projection images. The perfusion rate of the region of interest is then output to an output device, such as a display or printer.
