Setting an x-ray emission unit includes acquiring image data with the aid of a number of image recording units. A body region to be recorded of an examination object is identified based on the image data. Position data of the body region to be recorded is established, and the x-ray emission unit is set using the position data.

Setting an x-ray emission unit

The present invention is an x-ray arrangement for examining patients, having an x-ray source and a digital flat panel detector characterized by a processing unit with a converter with an input possibility for a whole data record of system parameters as input parameters which can be easily adjusted and input by the user for conversion into a whole data record of image chain parameters as output parameters.

X-ray arrangement with a converter and associated X-ray method

In a method, apparatus, and computer program encoded with a data structure, for processing radiographic images and digital fluoroscopy radiographic (DFR) images acquired with the same imaging system using a single detector, three different types of image orientation are defined. These are a 'system flip/rotation' that is dependent on the imaging system, a 'pre-flip/rotation' orientation that is applied before the images are shown on a monitor, and a &#x201c;post-flip/rotation&#x201d; that is applied after an image is shown on the monitor. For this orientation change, the original image must be stored and subsequently manipulated. For pre-processing, DFR images are subjected only to the system flip/rotation, whereas radiographic images are subjected to the system flip/rotation as well as the pre-flip/rotation. For post-processing, both the DFR images and the radiographic images are subjected to the post-flip/rotation.

X-ray image orientation in radiography and fluoroscopy

X-ray imaging systems can have different modes of operation. There is a calibration process for each mode of operation. Conventionally, the overall system is actuated during the calibration process in exactly the same way as when operating the x-ray imaging system () with the associated mode of operation. Individual calibration processes are now restricted to fixing a flat-panel parameter set which matches the mode of operation and by which the flat-panel detector () is actuated. However, the remaining system () does not have to be actuated depending on the mode of operation associated with the calibration process. A fixed system parameter set which is independent of the mode of operation is sufficient. It has been proven to be sufficient if no machine movements are carried out during all calibration processes, the x-ray radiation generator operates in the two-point technique and a series of images is recorded.
