Abstract
An X-ray K-edge subtraction television system utilizing synchrotron radiation is investigated. The phantom is irradiated by two monochromatized X-ray beams closely bracketing the K-absorption edge of iodine (33.17 keV) alternately, by means of a vibrating single crystal monochromator combined with a white synchrotron X-ray beam. The subtraction of the successive two images produced by these beams results in images that enhance signals arising from attenuation by iodine and suppresses signals by other materials. The prototype system is fully implemented using two kinds of real time image processing subsystems. The results are compared with those obtained by the conventional (nonreal time) processing system.Keywords
