    摘要: The invention relates to an X-ray detector with detector elements (1) arranged in a layer. The detector elements (1) contain a scintillator element (2) for the conversion of X-rays (X) into photons (v), a photodiode (5) for detection of the photons (v), and a processing circuit (4) for the processing of electric signals generated by the photodiode (5). In order to protect the electronics (4) from X-rays a shielding (3) of variable effective thickness (d1, d2) is disposed in front of the electronics (4). This shielding (3) can in particular be L-shaped. By reduction of the effective thickness of the shielding (3) to a necessary minimum the volume of the scintillator unit (2) can be maximized.

    摘要: The invention relates to an Anti-Scatter-Grid (1) that consists of carrier walls (10) and, transversal thereto, partition walls (20). Noses (22) of the partition walls (20) are inserted into holes (11) of the carrier walls (10) and fixed thereto by laser welding. The noses (22) preferably project from the backside of the carrier walls in order to facilitate welding and alignment. Moreover, various tools are proposed that assist the accurate assembling of the Anti-Scatter-Grid.

    摘要: The duration of use of spectrally sensitized pigment bonding agent layers which are to be used a number of times is substantially increased by performing floodlighting, after the development and/or transfer and prior to the recharging, with a light which is suitable per se for the image formation, but which is substantially not absorbed by the dye.
