We are building a tomographic x-ray scanner to inspect cast explosives and industrial parts and to study new materials. We will use the scanner to examine parts up to 38 cm, in height, 25 cm in diameter, and 25 kg in weight. We tested our reconstruction program by comparing the results of a computer experiment with the input data. The program can complete a 128-by-128 pixel reconstruction in about 10 minutes. The tomographic x-ray scanner rotates and translates the sample through a second-generation scan. We use a 32 -detector array with a 16-bit analog-to-digital converter purchased from Bio-Imaging Research. The detector and source are mounted on optical tables; one is a base for the entire assembly, and the other supports the detector array. We use an x-ray source from IRT Corporation with an output of 2 mA at 320 kV. The source spot size is 0.8 mm and the output is stable to {plus minus}1% over 5 hours. 6 figs.
