Abstract: In a method for correcting pixels of an x-ray image data set, an x-ray exposure of a subject is acquired with an x-ray device that uses a storage film having a luminescent storage material layer serving as a radiation detector. The sensitivity of the luminescent storage material layer changes dependent on the accumulated x-ray radiation dose to which the storage layer has been exposed. After acquiring the x-ray exposure, the storage film is readout with a readout device and an x-ray image data set is generated that corresponds on a pixel-by-pixel basis with the x-ray exposure. Each pixel of the x-ray image data set is corrected with a correction value allocated to the corresponding pixel in the x-ray exposure, the correction value being adapted to the accumulated x-ray radiation dose to which the region of the storage film, containing the corresponding pixel, was exposed prior to acquiring the x-ray exposure.

Abstract: A shield structure is provided that is suitable for use in connection with an x-ray device that includes an anode and cathode disposed in a vacuum enclosure in a spaced apart arrangement so that a target surface of the anode is positioned to receive electrons emitted by the cathode. The shield structure is configured to be interposed between the anode and the cathode and includes an interior surface that defines an aperture through which the electrons are passed from the cathode to the target surface of the anode. Additionally, the aperture includes an inlet and an outlet sized so that the area of the inlet is relatively smaller than the area of the outlet. Finally, the shield structure is situated in the x-ray device such that the inlet of the aperture is positioned near the cathode and the outlet of the aperture is positioned near the anode target surface.

Abstract: An encapsulated stator assembly for use in stator-driven devices is disclosed. The encapsulated stator assembly includes a stator and a covering portion that envelops the stator. The purpose of the covering portion is multi-fold: first, the covering portion serves as a means for mounting and securing the stator, such as within the outer housing of an x-ray tube. Second, the covering portion is thermally conductive to enable heat produced by the stator during operation to be dissipated to the outer housing of the x-ray tube thereof. Additionally, the covering portion can include an x-ray absorbent material to reduce x-ray emission from the x-ray tube. Though x-ray tubes represent one advantageous application, the encapsulated stator assembly of the present invention can be used in a variety of motor and stator-driven devices. The encapsulated stator assembly is especially well suited for use in dirty or dusty environments.
