A method is for producing a scattered beam collimator starting from a lower side and extending in a build-up direction as far as an upper side, and having a large number of X-ray absorbing partitions, and in which pass-through channels for unscattered X-ray radiation are embodied between the partitions. A lithographic process is used, by which the partitions of the scattered beam collimator are formed from a photoresist into which an X-ray absorbing material is mixed.
