Section: claims

1. A grid module of a scattered-radiation grid comprising a number of grid modules with webs arranged next to one another, a height of at least one of the webs disposed on an edge side in a respective one of the grid modules is relatively lower than a height of webs arranged further inwards in the respective grid module. 2. The grid module of claim 1, wherein a height of at least one further of the webs is embodied relatively increasing in height inwards in stages from an at least one edge side relatively lower web. 3. A detector of a CT system comprising a modular construction scattered-radiation grid, the scattered-radiation grid including the grid module of claim 1. 4. A CT system comprising a detector including a modular construction scattered-radiation grid, the scattered-radiation grid including grid modules of claim 1. 5. A scattered-radiation grid for an x-ray detector of a CT system including a plurality of detector elements disposed in rows and columns over its surface, comprising:at least two grid modules arranged next to one another, each of the at least two grid modules possessing a number of webs disposed next to one another with irradiation zones between them, and at least one edge-side web of at least one of the grid modules being adjacent to at least one other web disposed running in parallel next to one another on the edge side of another of the grid modules in absence of an irradiation zone arranged between them, webs running adjacent to each other including a relatively lower height than other webs. 6. The scattered-radiation grid of claim 5, wherein relatively lower height of the webs running adjacent to one another is dimensioned so that the proportion of scattered radiation additionally absorbed by the webs running adjacent to one another is compensated for by the reduced relative height of the webs. 7. The scattered-radiation grid of claim 5, wherein at least one further of the webs disposed further inwards in relation to the at least one grid module has a height which lies between the height of the webs disposed even further inwards and a web disposed further outwards. 8. The scattered-radiation grid of claim 7, wherein the relatively lower height of the webs arranged further inwards is dimensioned such that the proportion of scattered radiation additionally absorbed by the webs running adjacent to one another is compensated for by the reduced height of the webs. 9. The scattered-radiation grid of claim 5, wherein webs disposed exclusively in parallel to one another are provided. 10. The scattered-radiation grid of claim 5, wherein webs crossing each other at right angles are provided. 11. The scattered-radiation grid of claim 10, wherein the height of at least one web reduces in stages at its ends. 12. The scattered-radiation grid of claim 6, wherein at least one further of the webs disposed further inwards in relation to the at least one grid module has a height which lies between the height of the webs disposed even further inwards and a web disposed further outwards. 13. The scattered-radiation grid of claim 12, wherein the relatively lower height of the webs arranged further inwards is dimensioned such that the proportion of scattered radiation additionally absorbed by the webs running adjacent to one another is compensated for by the reduced height of the webs. 14. A detector of a CT system comprising the scattered-radiation grid of claim 5. 15. A CT system comprising a detector including the scattered-radiation grid of claim 5.
