【Abstract】 Objective To apply camera bellows in mobile developing of wrist X-ray photographs, taking photographs while developing in Kashin-Beck Disease(KBD) areas to improve the comprehensive quality of X-ray photographs.Methods After repeated proof and model experiments, the design was finalized, and the camera bellows was made of choice acid-proof, alkali-proof and anti-ageing materials, through delicate processing, applied in experimental developing of X-ray photographs of rats. After achieving obvious effect, it was used in field developing of X-ray photographs in endemic areas, and compared with single concentrated developing in dark rooms, to observe the difference of the two different methods in developing effect, and further examined the quality of X-ray photographs developed by camera bellows.Results The quality of concentrated development in dark rooms declined, with less top quality photos (56%) and more poor quality and waste photos. The rate of top grade field developing by camera bellows was up to 90%, with less poor quality and no waste photos.Conclusions The application of camera bellows successfully solved the problem of separated X-ray photographing and developing KBD areas, opened a new route for scientific photographing and field developing in endemic areas, and provided a new method for the implementation of mobile X-ray surveillance in diseases prevention and control.更多还原
