    摘要: A grid (1) for selective transmission of electromagnetic radiation and a method for manufacturing such grid is proposed. Therein, the grid (1) comprises a structural element with walls (3) comprising a plurality of particles (19) of a radiation-absorbing material wherein the particles (19) are sintered together such that pores (21) are present between neighboring particles (19). The pores (21) are at least partially filled with a second solid material. The filling of the pores (21) can be done by inserting the second material in a liquid, preferably molten form into the pores. The second material can be itself radiation-absorbing as well and may help to both, increase the mechanical stability of the grid and to enhance the radiation-absorbing properties.

    摘要: 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).

    摘要: The invention relates to an X-ray imaging device (100), particularly a Spectral-CT scanner, that comprises an X-ray source (10) for generating X-radiation with an energy spectrum (P(E,t)) which varies continuously during an observation period (T). In a preferred embodiment, the radiation (X) is attenuated in an object (1) according to an energy-dependent attenuation coefficient μ(E,r), the transmitted radiation is measured by sensor units (22) of a detector (20, 30), and the resulting measurement signal (i(t)) is sampled and A/D converted. This is preferably done by an oversampling A/D converter, for example a ΣΔ-ADC. The tube voltage (U(t)) that drives the X-ray source is sampled with high frequency. In an evaluation system (50), these sampled measurement values can be associated with corresponding effective energy spectra (Φ(E)) to determine the energy dependent attenuation coefficient μ(E,r).

    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.
