摘要： A collimator is disclosed for a radiation detector including at least three spacing elements arranged on a radiation exit face of the collimator. In at least one embodiment, they are embodied so as to mount the collimator in a stable manner with respect to a radiation converter of the radiation detector. The at least three spacing elements enable a very precise and stable alignment of the collimator in respect of the radiation converter despite manufacturing-related curves or unevennesses in the radiation exit face and/or the mounting surface on the part of the radiation converter. At least one embodiment of the invention also relates to a manufacturing method for such a collimator, as well as a method for manufacturing a radiation detector.

摘要： A photodiode array for a radiation detector is disclosed, including a multiplicity of photodiodes arranged in a structured fashion, the photodiodes respectively having an active pixel region for converting light into electrical signals. In at least one embodiment, a transparent oxide layer with a refractive index comparable to the photodiodes is arranged on the active pixel region of at least some of the photodiodes on a side of the photodiode array provided for arranging a scintillator array. Compared to known photodiode arrays, the oxide layer replaces an adhesive. As a result of equalizing the refractive indices, light incident on the interface between the oxide layer and the photodiode array is refracted or reflected to a lesser extent. This reduces the optical crosstalk between adjacent pixels. Moreover, the active pixel regions of the photodiodes become optically visible as a result of the oxide layer. This therefore provides conditions for precisely aligning the photodiode array relative to the scintillator array by way of optical monitoring. Overall, compared to known radiation detectors, this procedure can increase the effective light yield. At least one embodiment of the invention moreover relates to a corresponding method for producing such a photodiode array and such a radiation detector.

摘要： A method is disclosed for producing a 2D collimator element for a radiation detector, in which crossing webs made of a radiation-absorbing material are formed, layer-by-layer, by way of a rapid manufacturing technique. In at least one embodiment, the webs are aligned along a φ- and a z-direction and form a cell-shaped structure with laterally enclosed radiation channels, at least in the inner region of the 2D collimator element. In at least one embodiment, the invention moreover relates to a 2D collimator element for a radiation detector that has such a layered construction. This allows the provision of a very precise and rigid collimator arrangement which, at the same time, has a high collimation effect.
