Abstract
A collimator for a computer tomograph includes a number of collimator plates and a holder for the collimator plates. The collimator plates include, at the edge, a number of tabs spaced apart from one another. In a fashion corresponding to this, the holder has receptacles that are assigned to the tabs and that are spaced apart from one another, into which the tabs of the collimator plates engage. This configuration ensures highly accurate positioning of even long collimator plates.

A collimator for a computer tomograph, comprising:
- a number of collimator plates;
- and
- a holder for the collimator plates, wherein the collimator plates include, at an edge, a number of tabs spaced apart from one another, and wherein the holder includes tab receptacles assigned to the tabs and spaced apart from one another, into which the tabs of the collimator plates are adapted to engage;
- wherein
- the tab receptacles for two neighboring collimator plates are arranged offset from one another such that individual tab receptacles do not overlap in a direction normal to the neighboring collimator plates.
A collimator for a computer tomograph, comprising:
- a plurality of collimator plates, each including a plurality of tabs;
- and
- a holder for the collimator plates including a plurality of tab receptacles respectively adapted to receive the plurality of tabs of the collimator plates;
- wherein
- the tab receptacles for two neighboring collimator plates are arranged offset from one another such that individual tab receptacles do not overlap in a direction normal to the neighboring collimator plates.
A collimator for a computer tomograph, comprising:
- a plurality of collimator plates, each collimator plate including a plurality of tabs arranged on a first side and a plurality of tabs arranged on a second side;
- and
- a holder for the collimator plates, the holder including a plurality of tab receptacles, each tab receptacle being adapted to receive a tab of a collimator plate;
- wherein
- the tab receptacles for a first of two neighboring collimator plates are spaced apart from a side of the holder differently than tab receptacles for a second of the two neighboring collimator plates, and
- neighboring collimator plates are arranged in the holder rotated 180° relative to one another, the rotation being about a common central normal of the neighboring collimator plates.
