Abstract

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.
