    摘要： The device enables the detection of positions of the navigation marking elements on a reference star by way of at least two projection images taken by an X-ray system at different pivoting angles of a C-arm. The positions of the navigation marking elements on the reference star are also calculated by a navigation system tracking camera. The transformation from the coordinate system of the navigation system into the coordinate system of the X-ray system is calculated from the position of the reference star detected by the X-ray system and the position of the reference star detected by the tracking camera. The navigation marking elements are located outside of the volume which is reconstructed by way of the imaging process in order to prepare tomographic images. The positions of the navigation marking elements are determined from two-dimensional projections. All the navigation marking elements need only be detected by at least two projection images.

    摘要： A device and method are provided that enable calibration information to be determined for an x-ray apparatus that performs a three-dimensional x-ray scan. The calibration information is determined using an adapting method, wherein the adapting method is based on a position of an x-ray source relative to an x-ray unit marker device during image acquisition, an x-ray unit data set that describes the position of the x-ray unit marker device during image acquisition, and a two-dimensional calibration data set that describes at least one and preferably two actual two-dimensional x-ray images produced by irradiating a calibration object.

    摘要： The present invention relates to a method for determining calibration information which includes information on a spatial relationship between an x-ray apparatus reference frame and a three-dimensional scan reference frame, comprising the following steps: a three-dimensional calibration data set is provided which represents a three-dimensional calibration model of a calibration object in the three-dimensional scan reference frame, wherein the calibration model has been determined from scan data generated by a three-dimensional calibration x-ray scan, wherein in the three-dimensional calibration x-ray scan, an x-ray unit is moved along a three-dimensional scanning path relative to the calibration object, wherein at least a portion of the three-dimensional scanning path lies in the x-ray apparatus reference frame; x-ray source relative position data is provided which includes information on the relative position of an x-ray source relative to an x-ray unit marker device attached to the x-ray unit when actual two-dimensional x-ray images are produced; a two-dimensional calibration data set is provided which describes a first of the actual two-dimensional x-ray images which has been produced by means of irradiating at least the calibration object in a first position (FIG. 1) of the x-ray source in the x-ray apparatus reference frame, and which also describes: a) a second of the actual two-dimensional x-ray images which has been produced by means of irradiating at least the calibration object, which is spatially fixed as compared to the first two-dimensional x-ray image, in a second position (FIG. 2) of the x-ray source in the x-ray apparatus reference frame; and/or b) the dimensions of the calibration object; an x-ray unit data set is provided which describes the position of the x-ray unit marker device when the at least one actual two-dimensional x-ray image is generated; and the calibration information is determined by means of an adapting method on the basis of the x-ray source relative position data, the x-ray unit data set and the two-dimensional calibration data set.
