摘要： A method for operating an x-ray device, (e.g., a fluoroscope), is described herein. The method includes: creating planning information for a therapeutic intervention into a body vessel segment based on a reconstruction of the body vessel segment; providing the planning information to a processing unit of the x-ray device; providing the reconstruction of the body vessel segment to the processing unit; creating a recording of the body vessel segment introduced into a recording region of the x-ray device; registering the reconstruction of the body vessel segment with the body vessel segment in the recording region of the x-ray device; displaying the recording of the body vessel segment on a display device of the x-ray device; and superimposing a graphical representation of the planning information on the recording displayed on the display device, in order to increase the efficiency of the therapeutic intervention into the body vessel segment.

摘要： The disclosure relates to an X-ray machine and a method for the operation of the X-ray machine for generation of a three-dimensional reconstruction of a body part. The method includes supplying a first X-ray capture of the body part; an automatic analysis of the first X-ray capture; an evaluation of the suitability of at least one further capture angle by the computing unit in the light of a result from the automatic analysis; setting of a second capture angle on the X-ray machine, either automatically by the computing unit or manually by an operator; a manually controlled approach to the set second capture angle by a capture unit of the X-ray machine; and capture of the second X-ray capture from the approached second capture angle by the capture unit to provide an improved method for operation of an X-ray machine for generation of a three-dimensional reconstruction of a body part.

摘要： An X-ray imaging apparatus has at least one X-ray image system rotatable about an examination volume. The X-ray image system is controlled such that during a continuous rotation of the system, at least one 2D projection image is recorded. An image generation facility generates the 2D projection image from the measured data. The X-ray source includes an X-ray focus which can be changed in terms of position, which, during the recording of the 2D projection image, moves counter to the direction of rotation of the X-ray image system such that its spatial position in a fixed coordinate system does not change. The X-ray detector records several 2D partial images, from which the 2D projection image is calculated with the rotational movement of the X-ray detector being at least approximately compensated. The 2D projection images have significantly reduced image blur.

摘要： A system and method of obtaining perfusion data for cerebral tissue is described. The system includes a C-arm X-ray device and a computing system configured to obtain sets of rotational projection X-ray data suitable for reconstructing 3D voxel data sets. A first data set is obtained of the patient, and then contrast material is injected into the vascular system to obtain a second 1 data set. A first voxel data set is subtracted from the second voxel data set, and the resultant data set is processed so as to segment the contrast-enhanced vasculature from the remaining data. The segmented voxels are subtracted from the resultant voxel data set, so as to yield a functional data set representing the difference between the attenuation of the tissues after administering contrast agent and the tissues prior to administering the contrast agent, without the contrast enhanced vasculature. The attenuation of the functional data set represents the perfusion or cerebral blood volume (CBV).

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： A method and an X-ray image acquisition system for the acquisition of X-ray images of a region of interest of an examination object from a multiplicity of angles of view for an 3-D image reconstruction are provided. The X-ray image acquisition system comprises an X-ray focus and an X-ray detector, which can be separately positioned and oriented relative to each other. The X-ray focus is moved along a combination of straight line segments and/or arc segments for the acquisition of X-ray images. The X-ray detector is oriented relative to the X-ray focus and moved in such a way that the region of interest is projected completely onto the X-ray detector upon each image acquisition.
