    摘要: A method is proposed for producing an anti-scatter grid or collimator for a radiation type, which is formed from at least one base body of prescribable geometry having transmission channels or slits for primary radiation of the radiation type which extend between two opposite surfaces of the base body. The base body is formed from a structural material that strongly absorbs the radiation type, either using the injection molding technique or by way of the technique of stereolithography. The method can be used to produce an anti-scatter grid or collimator with high accuracy and with the aid of only a few steps.

    摘要: An X-ray detector is for a CT device and includes a phosphor layer for generating electromagnetic radiation as a function of the occurrence of X-radiation, and a photodetector layer for detecting the electromagnetic radiation generated by the phosphor layer. The phosphor layer includes ceramic material and the photodetector layer includes organic material. A process is further for producing an X-ray detector, including the steps of producing a phosphor layer from a ceramic material and applying a photodetector layer made from an organic material to the phosphor layer via a spinning, printing or beam/jet process or by sticking it on as a film. It is optionally possible to provide a further process step for polishing the surface of the phosphor layer before applying the photodetector layer.

    摘要: An image detector is for detecting electromagnetic radiation, in particular X-ray radiation. It includes a carrier layer and a photosensor carried by the carrier layer. Each of the carrier layer and photosensor both have a nonvanishing transparency to the electromagnetic radiation. The image detector includes two or more carrier layers and photosensors carried thereby, arranged one above the other, so that the electromagnetic radiation can pass through them one after the other.

    摘要: A method is for operation of a counting radiation detector, in particular of a counting X-ray detector, with improved linearity, in which each detector element of the counting radiation detector supplies counting pulses at counting rates as a function of a number of radiation quanta which occur per unit time during operation. In the method, the counting rates which are supplied from each detector element or from subsections of the detector element are converted via a functional relationship to actual counting rates or are multiplied by correction factors which are dependent on the magnitude of the counting rates. The correction factors are determined in advance for the respective detector element or for the subsections of it, and any discrepancy (which occurs as a result of a dead time of the detector element, for example) in the counting rates is corrected from the actual number of radiation quanta which arrive per unit time. The method allows the linearity of counting radiation detectors to be improved, particularly at high radiation intensities, so that the linearity condition for X-ray CT systems is also satisfied.

    摘要: A detector module is for CT and/or PET and/or SPECT examinations, and includes a number of measuring channels. Each measuring channel includes a direct converter for directly converting incident measuring radiation into analog electric signals, a pulse generator connected to the direct converter, for generating counting pulses as a function of the received electric signals, and a counting device that counts the received counting pulses over a prescribable time period and outputs the result. Arranged between the counting device and the pulse generator is an externally drivable changeover unit that can be used to switch over between the counting device and an event detector that registers and outputs for each received counting pulse the time and the associated measuring channel or an item of location information assigned to this measuring channel. The present detector module is of simple design.
