Abstract

A radiation detector includes an intermediate layer, which is arranged between a detection layer with a number of detection elements and a number of readout units. In an example embodiment of this arrangement, the intermediate layer has a plurality of electrically-conductive connections between the detection elements and the readout units. An example embodiment further specifies a medical imaging system, as well as a method of using the heating apparatus.

First claim

What is claimed is:

1. A radiation detector comprising:
a detection layer including a plurality of detection elements;
at least one readout unit;
an intermediate layer, arranged between the detection layer and the at least one readout unit, the intermediate layer including a plurality of electrically-conductive connections each respectively arranged between respective ones of the plurality of detection elements and the at least one readout unit; and
a heating apparatus, including at least one heating element, arranged between the detection layer and the at least one readout unit, wherein the at least one heating element is embodied as a serpentine electrical conductor that extends along two planar side surfaces of the intermediate layer.

2. The radiation detector of claim 1 , wherein an overall surface of the plurality of detection elements is relatively large compared to an overall surface of the at least one readout unit.

3. The radiation detector of claim 2 , wherein the radiation detector is embodied for detection of X-ray radiation.

4. The radiation detector of claim 1 , wherein the radiation detector is embodied for detection of X-ray radiation.

5. The radiation detector of claim 1 , wherein the plurality of electrically-conductive connections are embodied as vias and rewiring structures.

6. The radiation detector of claim 5 , wherein the intermediate layer includes the rewiring structures on a side facing towards the at least one readout unit.

7. The radiation detector of claim 1 , wherein the intermediate layer comprises a substrate made from at least one of a glass fiber composite material, phenolic paper, ceramics and glass.

8. The radiation detector of claim 1 , further comprising a support structure, including a plurality of elements configured to forward data from the at least one readout unit.

9. The radiation detector of claim 8 , wherein the support structure is a conductive support.

10. The radiation detector of claim 1 , wherein the heating apparatus comprises a control device, configured to regulate heating power introduced into the radiation detector.

11. The radiation detector of claim 1 , wherein the heating apparatus includes a plurality of heating elements distributed evenly in areas over a surface of the detector layer.

12. The radiation detector of claim 1 , wherein the at least one heating element is configured to introduce both a positive heating power and a negative heating power into the detector layer.

13. The radiation detector of claim 1 , wherein the at least one heating element is arranged in the shape of a rectangle function alternating in turn on an upper surface and a lower surface of the intermediate layer.

14. The radiation detector of claim 1 , wherein the at least one heating element is arranged in a recess in the intermediate layer.

15. The radiation detector of claim 1 , wherein the at least one heating element is arranged between the plurality of electrically-conductive connections.

16. A medical imaging system comprising the radiation detector of claim 1 .

17. The radiation detector of claim 1 , wherein the heating element passes from one of the two planar side surfaces of the intermediate layer to the other of the two planar side surfaces of the intermediate layer and passes between vias that traverse through the intermediate layer.
