1. An apparatus for ascertaining a material feature associated with a subject, the apparatus comprising:
- a first carriage and a second carriage, each carriage including a source adapted to produce a beam of penetrating radiation incident on the subject;
at least one vertical positioner adapted to synchronously displace each carriage with respect to the subject in a direction having a vertical component; and
at least one detector for receiving radiation produced by at least one of the sources after interaction of the radiation with the subject.

Abstract
An apparatus and method for inspecting personnel or their effects. A first and second carriage each carries a source for producing a beam of penetrating radiation incident on a subject. A positioner provides for synchronized relative motion of each carriage vis-à-vis the subject in a direction having a vertical component. A detector receives radiation produced by at least one of the sources after the radiation interacts with the subject.

25. An apparatus for ascertaining a material feature associated with a subject, the apparatus comprising:
-
a first carriage having coupled to it; a source adapted to produce a beam of penetrating radiation incident on a subject, and a first detector for detecting penetrating radiation scattered by the subject a second carriage having a second detector for detecting penetrating radiation produced by the source of the first carriage and transmitted through the subject; and at least one vertical positioner adapted to synchronously vary the position of each carriage with respect to said subject in a direction having a vertical component. - View Dependent Claims (26)

27. An apparatus for ascertaining a material feature associated with a subject, the apparatus comprising:
-
two vertically disposed arrays of sources adapted to produce beams of penetrating radiation; at least one detector for receiving radiation produced by at least one of the sources after interaction of the radiation with the subject; and a controller for activating at least one source in at least one of the arrays independent from the other sources in the same array. - View Dependent Claims (28, 29)

30. A method for inspecting a subject comprising:
-
moving a first carriage, the first carriage having coupled to it a first source adapted to produce a beam of penetrating radiation incident on the subject; moving, in synchronization with the first carriage, a second carriage, the second carriage having coupled to it a second source adapted to produce a beam of penetrating radiation; detecting, with at least one detector, radiation produced by at least one of the sources after interaction of the radiation with the subject; generating detector output signals based on radiation received by the at least one detector; and characterizing the subject on the basis of the detector output signals. - View Dependent Claims (31, 32, 33, 34, 35)

36. A method for inspecting a subject comprising:
-
generating beams of penetrating radiation at a temporally varying elevation, the beams of penetrating radiation generated by at least one first source positioned to direct the radiation in a first direction toward the subject and at least one second source positioned to direct penetrating radiation in a second direction toward the subject; and detecting with the at least one detector the radiation produced by at least one of the sources after interaction of the radiation with the subject. - View Dependent Claims (37)
