    Abstract: A method and an apparatus for locally applying material to the surface of an anode of an X-ray source as well as a corresponding anode is presented. Anode material such as a repair material for filling a recess (121) in an X-ray emitting surface (115) is applied to the X-ray emitting surface of an anode (101). The location where such material is to be applied may be detected using a laser beam (133). The applied repair material including particles (41) of anode material such as tungsten, rhenium or molybdenum, is subsequently locally sintered using a high-energy laser beam (151). The sintered material may then be melted using a high-energy electron beam (163). Using such method, a damaged surface of an anode may be locally repaired. Alternatively, structures of different anode materials or of protrusions having different levels can be provided on the X-ray emitting surface (115) in order to selectively manipulate the X-ray emitting characteristics of the anode (101).

    Abstract: The invention relates to an Anti-Scatter-Grid (ASG) with lamellae (2) that absorb incident radiation (1, 8) and that produce an electrical signal proportional to the amount of absorbed radiation. The lamellae (2) may particularly consist of a semiconductor material in which photons produce electron-hole pairs that can be detected with the help of electrodes (3, 4, 6) on the sidewalls of the lamellae (2). The amount of absorbed scattered (8) or primary (1) radiation may thus be determined in a spatially resolved way, allowing to correct the image generated by an array (5) of sensor units (9).

    Abstract: The invention relates to an X-ray detector with an array of pixels (10) that are composed of a scintillation layer (11), a coupling layer (12), and a sensitive layer (13). The coupling layer (12) comprises light guiding units (17) and shielding units (16), wherein the shielding units (16) are disposed above electronic processing circuits (15a, 15b) that are susceptible to disturbances by X-radiation. In an alternative embodiment, the coupling layer comprises a material like lead-glass that is transparent for light and absorbing for X-radiation. Preferably a wavelength- shifting material incorporated into the coupling layer (12) shifts the wavelength (? 1 ) of the photons generated in the scintillation layer (11) to values (? 2 ) at which the sensitive layer (13) has a higher sensitivity.
