Abstract: In order to increase the useful surface of an X-ray detector, in particular a flat image detector, a method is provided for gain calibration of an X-ray imaging system with a digital X-ray detector including an active matrix having pixel readout units. Pixels are read out from the pixel readout units, and a brightness drop below a defined threshold is determined for the read out pixels by an image processing unit. The pixel readout units having a brightness drop below the defined threshold are specified with regard to a cause of the brightness drop. Further, as a function of the specification, it is defined for which image raw values, subsequently read out from the affected pixel readout units, a gain correction is to be undertaken.

Abstract: By a contrast means contained in an inventive stent which has a greater permeability for x-radiation features than the body tissue surrounding the stent in a relevant body conduit, this stent can be clearly detected in its position on an x-ray image of the relevant body conduit while at the same time exhibiting good biological compatibility; a gas, especially one contained in cavities of the stent is provided as a contrast means. The inventive production method for this stent with the aid of a catheter embodied specially for the purpose enables the production of the stent from a malleable polymer mass in the relevant body conduit so that the stent is adapted especially precisely to the shape of the relevant body conduit.

Abstract: There is described a radiography device for recording dynamic processes and an associated recording method. The radiography arrangement is used to examine patients using an x-ray source, a digital flat detector with a single shot recording function and an operating console for controlling and recording purposes, with the flat detector also being able to display an image sequence at a rate of up to 5 Hertz, which allows the positioning of the region to be examined or the monitoring of pseudo-interventional interventions.

Abstract: During tomosynthesis a plurality of x-ray images is acquired. The angular position of the x-ray tube is changed from x-ray image to x-ray image. Absorption in the imaged object (patient) and also in the patient table changes as a function of the angle. To compensate for this, backlight is applied while the x-ray images are being acquired. The intensity of the back light is selected as a function of the angle of the x-ray tube to the normal of the flat x-ray detector. Backlight can also be directed during reading, with only the areas already read in each instance being irradiated.

Abstract: In a method to create a gain-corrected x-ray image with the aid of a flat-panel x-ray detector a number of gain images are determined on calibration and this is done for different measurement situations which correspond to different settings of specific x-ray imaging variables such as the angle of the flat-panel x-ray detector to an x-ray tube, the energy of the x-radiation used etc. Instead of the usual gain image for each element of the detector, a gain value is then used in the gain correction which is produced from an interpolation of the corresponding values from the number of gain images.
