Abstract

A method for scanning an individual with a security device includes providing a scanner, engaging the scanner in a first scanning mode to produce an initial scan of the individual with a controller, producing an initial representation based on the initial scan, determining a property of a second scanning mode based on information from the initial representation, and engaging the scanner in the second scanning mode to produce a second scan of the individual.

Claims

1. A method, comprising:

engaging a scanner in a first scanning mode that includes a first scanning of a standing individual with a first scanning beam of electromagnetic waves;

receiving a return of the first scanning beam of electromagnetic waves from the standing individual;

producing a representation of the standing individual based on the returned first scanning beam of electromagnetic waves;

determining a property of a second scanning mode based on the representation;

engaging the scanner in the second scanning mode that includes a second scanning of the standing individual with a second scanning beam of electromagnetic waves;

receiving a return of the second scanning beam of electromagnetic waves from the standing individual;

determining a threat that the standing individual carries contraband based upon the returned second scanning beam of electromagnetic waves; and

outputting a human-perceivable notification of the determined threat.

2. The method of claim 1, further comprising determining a maximum allowable dosage for the individual based on a characteristic of the individual and a maximum dose exposure limit for the individual.

3. The method of claim 1, further comprising determining an allowable dosage with the controller based on a characteristic of the individual.

4. The method of claim 1, further comprising determining a maximum allowable dosage for the individual based on a characteristic of the individual.

5. The method of claim 1, wherein the property includes a dose that may be received by the individual.

6. The method of claim 5, wherein the dose that may be received by the individual during the second scanning mode is greater than the dose that may be received by the individual during the first scanning mode.

7. The method of claim 1, wherein the property includes a target area of the individual.

8. The method of claim 7, wherein the target area of the individual corresponds to a portion of the initial representation having an image quality that is at least one of less than other portions of the initial representation and below a threshold level.

9. The method of claim 7, wherein the target area of the individual corresponds to a portion of the initial representation potentially indicating a suspect object.

10. The method of claim 1, further comprising determining a characteristic of the individual with the controller using the initial scan.

11. The method of claim 10, wherein the characteristic includes at least one of age, gender, weight, a medical condition, and body structure.

12. The method of claim 10, wherein the characteristic includes a pregnancy status.

13. The method of claim 1, wherein the first scanning mode comprises a physiological scan.

14. The method of claim 13, further comprising determining at least one of a body temperature of the individual and a stress level of the individual with the physiological scan.

15. The method of claim 1, wherein the first scanning mode comprises at least one of an optical scan, a biometric identification scan, and an infrared scan.

16. The method of claim 1, wherein the first scanning mode comprises at least one of a microwave scan, an ultrasound scan, and a radiofrequency scan.

17. The method of claim 1, wherein the first scanning mode comprises at least one of a backscattering x-ray scan and a transmissive x-ray scan.

18. The method of claim 1, wherein the standing individual includes a standing individual entering a secured area.

19. The method of claim 1, wherein the standing individual includes a free-standing individual.

20. The method of claim 1, wherein the standing individual includes an unsupported individual.

21. A security device, comprising:

a scanner configured to transmit at least two selectable scanning beams of electromagnetic waves at a standing individual, and to receive returned electromagnetic waves from the standing individual;

a controller configured to;

engage the scanner in a first scanning mode that includes a first scanning of the standing individual with a first scanning beam of electromagnetic waves;

receive a return of the first scanning beam of electromagnetic waves from the standing individual;

produce a representation of the standing individual based on the returned first scanning beam of electromagnetic waves;

determine a property of a second scanning mode based on the representation;

engage the scanner in a second scanning mode that includes a second scanning of the standing individual with a second scanning beam of electromagnetic waves;

receive a return of the second scanning beam of electromagnetic waves from the standing individual; and

determine a threat that the standing individual possesses contraband based upon the returned second scanning beam of electromagnetic waves; and

an indicator device configured to output a human-perceivable alert of the determined threat.

22. The security device of claim 21, wherein the controller is configured to determine a maximum allowable dosage for the individual based on a characteristic of the individual and a maximum dose exposure limit for the individual.

23. The security device of claim 21, wherein the controller is configured to determine an allowable dosage with the controller based on a characteristic of the individual.

24. The security device of claim 21, wherein the controller is configured to determine a maximum allowable dosage for the individual based on a characteristic of the individual.

25. The security device of claim 21, wherein the property includes a dose that may be received by the individual.

26. The security device of claim 25, wherein the dose that may be received by the individual during the second scanning mode is greater than the dose that may be received by the individual during the first scanning mode.

27. The security device of claim 21, wherein the property includes a target area of the individual.

28. The security device of claim 27, wherein the target area of the individual corresponds to a portion of the initial representation having an image quality that is at least one of less than other portions of the initial representation and below a threshold level.

29. The security device of claim 27, wherein the target area of the individual corresponds to a portion of the initial representation potentially indicating a suspect object.

30. The security device of claim 21, wherein the controller is configured to determine a characteristic of the individual with the controller using the initial scan.

31. The security device of claim 30, wherein the characteristic includes at least one of age, gender, weight, a medical condition, and body structure.

32. The security device of claim 30, wherein the characteristic includes a pregnancy status.

33. The security device of claim 21, wherein the first scanning mode comprises a physiological scan.

34. The security device of claim 33, wherein the controller is configured to determine at least one of a body temperature of the individual and a stress level of the individual with the physiological scan.

35. The security device of claim 21, wherein the first scanning mode comprises at least one of an optical scan, a biometric identification scan, and an infrared scan.

36. The security device of claim 21, wherein the first scanning mode comprises at least one of a microwave scan, an ultrasound scan, and a radiofrequency scan.

37. The security device of claim 21, wherein the first scanning mode comprises at least one of a backscattering x-ray scan and a transmissive x-ray scan.
