摘要： In flat-panel X-ray detectors which have a multiplicity of detector elements which are in each case associated with one pixel of an X-ray image, the individual detectors generate offset signals. These offset signals are detected by recording offset images in which there is no X-ray irradiation (dark images). The offset images are recorded after the X-ray images to be corrected in time. If for each X-ray image record, an associated offset image record is generated by using a single offset image or of two, the offset images can be recorded closely in time. Ghosting effects are then not disturbing because the offset images are only used for correcting the X-ray images which cause the ghosting.
摘要翻译：在具有多个检测器元件的平板X射线检测器中，每个检测器元件在每种情况下与X射线图像的一个像素相关联，各个检测器产生偏移信号。通过记录不存在X射线照射的偏移图像（暗图像）来检测这些偏移信号。在X射线图像之后记录偏移图像以便及时校正。如果对于每个X射线图像记录，通过使用单个偏移图像或两个偏移图像生成相关联的偏移图像记录，可以及时记录偏移图像。然后，重影效果不会受到影响，因为偏移图像仅用于校正造成重影的X射线图像。

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
