The imaging system

The image is acquired by the detector depending on the spectral distributions of the x-ray source. The individual objects are characterized by their material properties, such as atomic composition, density and thickness. The detector converts x-ray photons to visible light photons then photodiode converts the visible photons to electrical current that is amplified and sampled, forming the final image.

The system uses a collimator to transform the conical beam of the x-ray source into the x-ray source which consists of an x-ray tube. The x-ray tube generates the x-rays, which emanate from the tube mouth in a conical shape. The x-ray spot repeatedly scans the x-ray inspection area in a vertical direction, allowing the use of a single large area sensor for the detector, the sensor is interfaced with digitizing boards. Each digitizing board creates successive 1-dimensional slices of a scanned object that are appended together to create a 2- dimensional image.

An image processing algorithms to determine the true x-ray intensities will be developed.
