Radiation scanning units including a movable platform
First Claim
1. A scanning unit for inspecting objects, comprising:
- a movable platform to support an object;
a radiation source to emit a beam of radiation toward the object;
a detector positioned to receive radiation after interaction with object;
wherein the platform is movable at least partially within a cavity defined, at least in part, below at least one of the source or the detector.

Abstract
A scanning unit for inspecting objects comprises in one example a radiation source, a movable platform to support an object, and a detector positioned to receive radiation after interaction of radiation with the object. The platform is movable at least partially within a cavity defined, at least partially, below at least one of the source or the detector. In another scanning unit, a first conveyor conveys an object to a movable platform, and second and third conveyors convey the object from the platform. The second and third conveyors are at different vertical heights. In another scanning unit, images from an energy sensitive detector and a spatial detector are fused. In a method, scanning parameters during CT scanning are changed and images reconstructed before and after the change. In another method, an object is scanned with X-ray beams having first and second energy distributions, generated by the same X-ray source.

15. A scanning unit for inspecting objects, comprising:
-
at least one source of penetrating radiation to emit a beam of radiation to scan an object; a movable platform to support an object during scanning by the beam of radiation; at least one detector positioned to receive radiation after interaction with the object; a first conveyor to convey the object to the platform for scanning; a second conveyor to convey the object from the platform after scanning, the second conveyor being at a first vertical height; and a third conveyor to convey the object from the platform after scanning, the third conveyor being at a second vertical height different than the first vertical height; wherein the platform is configured to selectively direct the object to one of the second conveyor or the third conveyor by moving the platform between the first height and the second height. - View Dependent Claims (16, 17, 18)

36. A method for inspecting objects, comprising:
-
scanning an object with a first beam of X-ray radiation from a radiation source, the first radiation beam having a first energy distribution; detecting first radiation after the first radiation beam interacts with the object; generating a first image based on the first detected radiation; causing the radiation source to generate a second beam of X-ray radiation, the second radiation beam having a second energy distribution different from the first energy distribution; scanning the object with the second radiation beam from the radiation source; detecting second radiation after the second beam interacts with the object; and generating a second image based on the second detected radiation.
