Abstract
In order to improve the image quality of flash X-ray images, a single step process "Computed Radiography" has been tested and evaluated. In this process, which has previously been used for medical imaging, the image intensifier screen is directly scanned by a laser beam into digital format, making the image directly accessible for computer evaluation. Results of the evaluation and descriptions on how the technique can be adapted for flash X-ray imaging are presented. The computed radiography technique has been tested in high speed and extreme dynamic applications with 150 kV and 450 kV Scandiflash flash X-ray tubes. Tests have been performed both for shadow and penetration imaging. The image plates showed to have higher dynamics, smaller grain size and being less sensitive to stray light and mechanical stress than common photographic film-screen system, resulting in an increase in resolution and decrease in noise.
