Abstract

A detector module is disclosed for an X-ray detector. In an embodiment, the detector module includes a number of sensor boards arranged adjacent to each other on a module support, each sensor board including, in a stack formation, a sensor layer having a sensor surface and a support ceramic by which the sensor layer is thermally coupled to the module support. A number of elements are arranged on the side of the support ceramic that faces the module support in a stack formation and at least one heating element is included which, in a plane of projection perpendicular to the stack formation, at least partially covers at least the area of the support ceramic that is free from the elements. An X-ray detector including a number of detector modules is also disclosed.

First claim

What is claimed is:

1 . A detector module for an X-ray detector comprising:
a number of sensor boards arranged adjacent to each other on a module support, each of the sensor boards including, in a stack formation,
a sensor layer including a sensor surface, and
a support ceramic, by which the sensor layer is thermally coupled to the module support, wherein a number of elements are arranged in a stack formation on a side of the support ceramic that faces the module support and wherein at least one heating element is included which, in a plane of projection perpendicular to the stack formation, at least partially covers at least an area of the support ceramic that is free from the elements.

2 . The detector module of claim 1 , wherein the heating element is designed as a meander-shaped heating loop.

3 . The detector module of claim 1 , wherein the heating element is arranged in a stack formation on at least one of a top and bottom of the support ceramic.

4 . The detector module of claim 1 , wherein the heating element is embedded in a stack formation in the support ceramic.

5 . The detector module of claim 1 , wherein at least one heat-conducting coating is arranged on the support ceramic.

6 . The detector module of claim 5 , wherein a heat-conducting coating is arranged on a top of the support ceramic.

7 . The detector module of claim 5 , wherein a heat-conducting coating is embedded in the support ceramic.

8 . The detector module of claim 5 , wherein the at least one heat-conducting coating is made from one or more metals which are chosen from a group that includes copper, nickel, indium, tungsten, aluminum and gold.

9 . The detector module of claim 1 , wherein a read unit is arranged in a stack formation between the sensor layer) and the support ceramic.

10 . The detector module of claim 1 , wherein the sensor layer comprises a direct-converting semi-conductor material.

11 . An X-ray detector for imaging an object penetrated by X-ray radiation, comprising a plurality of detector modules, at least one of the plurality of detector modules being the detector module of claim 1 .

12 . The X-ray detector of claim 11 , wherein the support ceramic is connected in a stack formation via the module support to an electronic sensor device.

13 . The detector module of claim 2 , wherein the heating element is arranged in a stack formation on at least one of a top and bottom of the support ceramic.

14 . The detector module of claim 13 , wherein the heating element is embedded in a stack formation in the support ceramic.

15 . The detector module of claim 14 , wherein at least one heat-conducting coating is arranged on the support ceramic.

16 . The detector module of claim 15 , wherein a heat-conducting coating is arranged on the top of the support ceramic.

17 . The detector module of claim 2 , wherein the heating element is embedded in a stack formation in the support ceramic.

18 . The detector module of claim 2 , wherein at least one heat-conducting coating is arranged on the support ceramic.

19 . The detector module of claim 6 , wherein a heat-conducting coating is embedded in the support ceramic.

20 . The detector module of claim 10 , wherein the direct-converting semi-conductor material is cadmium telluride (CdTe) or cadmium zinc telluride (CdZnTe).
