Abstract:
Objective To realize fully automatic X-ray exposure controlling,simplify operating processes,and improve the quality of images.Methods We designed 5 or 7 X-ray detectors with silicon batteries,improved film-holding board of the main engine of the X-ray machine,then assembled them by mechanical gearing,and thus made multi-measured-limit,automatically-changed X-ray detectors.Results When choosing film boxes according to the radiographed positions,the detectors will change automatically into measured-limits coinciding with the interested positions.The average density was around 1Ⅴ in 9 randomly selected photographs.High quality was achieved in up to 98% of 10 000 radiographed images for clinic radiography.Conclusion The key of X-ray automatic exposure controlling technology is X-ray detecting technology,by which the quality of image can be improved.
