| Abstract: | X-ray projectional images are very important in medical diagnostics and industrial nondestructive testing. The digitization of this technology is bound to see rapid development. An outline is given of the properties, principle, and application of X-ray digital radiography. The development of a 32-channel X-ray digital radiography system with Xenon gas ionization chamber array detector and spatial resolution of 0 5mm is described. Results of this imaging installation are presented. |
