A detector is disclosed, including at least one scintillator and at least one photodiode, connected to one another by a connecting medium. The scintillator has a defined depression for holding the connecting medium on its side facing the photodiode in such a way that the visible light produced by the scintillator is focused in the direction of the photodiode. The detector is provided for an imaging X-ray unit, for example a computed tomography unit.

Detector with a scintillator, and imaging unit having such a detector

An x-ray detector with a scintillator element connected to a detection area of a photodiode via an optically transparently curing adhesive. To increase the sensitivity of the x-ray detector, it is proposed to mix the adhesive with a powder prepared from a material with a refractive index of at least 1.8 and an average grain size of less than 100 nm.

A collimator is disclosed. The ends of collimator plates are potted with the aid of a top plate and a bottom plate with the formation of interspaces, defined by spacings, between the collimator plates. When producing such a collimator, the top and bottom plates are produced using a casting method, and the collimator plates are simultaneously cast in, in order to fix them in the bottom and top plates. For this production method, a reusable holding apparatus that holds the collimator plates, and a casting mold are provided for aligning and positioning purposes.
