The liquid material may be contained within a container positioned within the recess. Preferably, the article is an insert for a security screening tray.

A method for imaging a sample by means of an X-ray detector is disclosed, including providing an electron beam interacting with a target to generate X-ray radiation emitted from an X-ray spot on the target, moving the sample relative to the target, deflecting the electron beam such that the X-ray spot is moved over the target simultaneously and in accordance with the movement of the sample, and detecting X-ray radiation emitted from the X-ray spot and interacting with the sample.

There are described herein methods and system for generating an inspection image of an object from radiographic imaging. The method comprises obtaining a plurality of digital images of the object positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images, and forming the inspection image from image features common to the digital images at a common scale and removing the unique grain diffraction patterns.

Provided is a detector capable of appropriately and highly accurately detecting radiation even under an environment where a wide range of radiation is irradiated.

The radiation detector is configured in such a manner that a plurality of light receiving devices are arranged in each cell of a scintillator that is divided into a plurality of cells, photoelectric conversion of scintillation light emitted by each individual cell is dividedly performed by the plurality of light receiving devices to reduce a charge amount of an output signal of each light receiving device, and the output signals are input into an integrated circuit to generate a radiation detection signal of each cell.
