Abstract

Systems and methods for reducing a degradation effect on a signal are described. One of the methods includes pre-processing data based on a scan of a reference object and a scan of a substance. The reference object includes a material having an atomic number ranging from and including forty to sixty.

Claims (32)

1. A method for reducing a degradation effect on a signal, said method comprising:

placing a reference object within a housing;

pre-processing data based on a scan of the reference object and a scan of a substance, wherein the reference object includes a material having an atomic number ranging from and including forty to sixty, wherein data is pre-processed as a function of an intensity of scattered radiation detected by a detector element upon scanning the substance, an intensity of scattered radiation detected by the detector element upon scanning the reference object, a Photoelectric pathlength of the substance, a Compton pathlength of the substance, a Photoelectric pathlength of the reference object, and a Compton pathlength of the reference object.

2. A method in accordance with claim 1 , further comprising wherein placing a reference object within a housing comprises confining the reference object within a housing that is opaque to light.

3. A method in accordance with claim 1 , further comprising scanning the material comprising silver.

4. A method in accordance with claim 1 , further comprising scanning the reference object comprising a silver nitrate solution.

5. A method in accordance with claim 1 , further comprising scanning the reference object by using a dual-energy transmission detector.

6. A system for reducing a degradation effect on a signal, said system comprising:

an X-ray source configured to generate X-rays;

a reference object configured to output scattered radiation upon receiving the X-rays, the reference object comprising a material having an atomic number ranging from and including forty to sixty;

a housing configured to contain the reference object;

a detector configured to output an electrical signal by detecting the scattered radiation; and

a processor coupled to said detector, said processor configured to generate data as a function of an intensity of the scattered radiation from the reference object and an intensity of scattered radiation from a scanned substance, a Photoelectric pathlength of the substance, a Compton pathlength of the substance, a Photoelectric pathlength of the reference object, and a Compton pathlength of the reference object.

7. A system in accordance with claim 6 , wherein the reference object comprises a solution of silver nitrate.

8. A system in accordance with claim 6 , wherein the reference object comprises a dilute solution of silver nitrate.

9. A system in accordance with claim 6 , wherein the material comprises silver.

10. A system in accordance with claim 6 , wherein said housing comprises a plastic material.

11. A system in accordance with claim 6 , wherein said housing is configured to hermetically seal the reference object.

12. A system in accordance with claim 6 , wherein said housing is opaque to light.

13. A method for reducing a degradation effect on a signal, said method comprising generating pre-processed data as a function of an intensity of scattered radiation detected by a detector element upon scanning a substance, an intensity of scattered radiation detected by the detector element upon scanning a reference object, a Photoelectric pathlength of the substance, a Compton pathlength of the substance, a Photoelectric pathlength of the reference object, and a Compton pathlength of the reference object.

14. A method in accordance with claim 13 , further comprising scanning the reference object including a material having an atomic number ranging from and including forty to sixty.

15. A system for reducing a degradation effect on a signal, said system comprising:

an X-ray source configured to generate X-rays;

a reference object configured to output a first set of transmission radiation and scattered radiation upon receiving the X-rays;

a substance configured to output a second set of transmission radiation and scattered radiation upon receiving the X-rays;

a dual-energy transmission detector configured to detect the transmission radiation within the first and second sets;

a scatter detector comprising a detector element and configured to detect the scattered radiation within the first and second sets;

a processor coupled to said dual-energy transmission detector and said scatter detector, wherein said processor is configured to generate pre-processed data as a function of an intensity of the scattered radiation within the first set, an intensity of the scattered radiation within the second set, a Photoelectric pathlength of the substance, a Compton pathlength of the substance, a Photoelectric pathlength of the reference object, and a Compton pathlength of the reference object.

16. A system in accordance with claim 15 , wherein the reference object comprises a solution of silver nitrate.

17. A system in accordance with claim 15 , wherein the reference object comprises a dilute solution of silver nitrate.

18. A system in accordance with claim 15 , wherein the reference object comprises silver.

19. A system in accordance with claim 15 , further comprising a reference object housing configured to confine the reference object, wherein the reference object housing is hermetically sealed.
