Abstract: The present specification describes a system for synchronizing a transmission detector and a backscatter detector integrated with a portable X-ray scanner. The system includes a transmitter connected with the transmission detector for transmitting the analog detector signal and a receiver connected with the scanner for receiving the transmitted analog detected signal where the transmitter and the receiver operate in the ultra-high frequency range.

Abstract: The present specification provides a detector for an X-ray imaging system. The detector includes at least one high resolution layer having high resolution wavelength-shifting optical fibers, each fiber occupying a distinct region of the detector, at least one low resolution layer with low resolution regions, and a single segmented multi-channel photo-multiplier tube for coupling signals obtained from the high resolution fibers and the low resolution regions.

Abstract: Methods for inspecting contents of a container. High-energy penetrating radiation collimated into a fan beam illuminates an inspected container from one side, while a plurality of detector plates are disposed on the opposite side of the container. Each detector plate has a plurality of detector modules, each of which, in turn, is disposed on a remotely activated alignment and has multiple detector elements. A controller governs the orientation of each of the plurality of detector plates based at least on the detector signal generated by its detector elements such that each detector element of each detector module of each detector plate may be aligned to within a specified fraction of the transverse dimension of the fan beam as measured at the exit slot.
