Abstract

An adaptive X-ray filter for varying a local intensity of X-ray radiation includes a first chamber containing a magnetorheological or electrorheological first liquid, a second chamber containing a second liquid that absorbs X-ray radiation, and a flexible membrane that separates the first chamber from the second chamber. Using the flexible membrane, a layer thickness ratio of the first liquid and the second liquid may be varied. A heating apparatus that heats the second liquid is arranged in the adaptive X-ray filter. The second liquid is a liquid metal.

Claims (19)

1. An adaptive X-ray filter for varying a local intensity of X-ray radiation, the adaptive X-ray filter comprising:

a first chamber comprising a first liquid;

a second chamber comprising a second liquid, wherein the second liquid is a liquid metal and is operable to absorb X-ray radiation;

a flexible membrane operable to separate the first chamber from the second chamber, and operable to vary a layer thickness ratio of the first liquid and the second liquid; and

a heating apparatus operable to heat the second liquid.

2. The adaptive X-ray filter of claim 1 , wherein the first liquid is a magnetorheological fluid.

3. The adaptive X-ray filter of claim 1 , wherein the first liquid is an electrorheological fluid.

4. The adaptive X-ray filter of claim 1 , further comprising a housing, in which the first chamber and the second chamber are constructed.

5. The adaptive X-ray filter of claim 4 , wherein the heating apparatus comprises a heating unit adjacent to the second chamber.

6. The adaptive X-ray filter of claim 5 , further comprising an electrode matrix operable to apply an electrical field or a magnetic field to the first liquid.

7. The adaptive X-ray filter of claim 5 , further comprising a pump device operable to vary a ratio of the pressure in the first chamber, the second chamber, or the first chamber and the second chamber.

8. The adaptive X-ray filter as claimed in claim 5 , wherein the heating unit comprises a heating coil and a thermostat.

9. The adaptive X-ray filter of claim 4 , further comprising an electrode matrix operable to apply an electrical field or a magnetic field to the first liquid.

10. The adaptive X-ray filter of claim 4 , further comprising a pump device operable to vary a ratio of the pressure in the first chamber, the second chamber, or the first chamber and the second chamber.

11. The adaptive X-ray filter of claim 1 , further comprising an electrode matrix operable to apply an electrical field or a magnetic field to the first liquid.

12. The adaptive X-ray filter as claimed in claim 11 , wherein the heating unit comprises a heating coil and a thermostat.

13. The adaptive X-ray filter of claim 1 , further comprising a pump device operable to vary a ratio of the pressure in the first chamber, the second chamber, or the first chamber and the second chamber.

14. The adaptive X-ray filter as claimed in claim 13 , wherein the heating unit comprises a heating coil and a thermostat.

15. The adaptive X-ray filter of claim 1 , wherein the second fluid comprises a colloidal solution.
