Analysis of the Application Effect of Mobile Camera Bellows

ZHANG Hua fang, LI Heng xiang, CHONG Guan feng (Shandong Institute for Endemic Disease Control and Research, Jinan, Shandong 250014, China)  
To interpret scientific value of synchro wielding mobile X ray photographing and field developing in Kashin beck disease areas and popularize mobile camera bellows, we observed the difference of the quality of development in dark room and field development by mobile camera bellows following camera bellow popularized. Because development in dark room could not work in the ground of X ray photographing, it lost the function of supervision and control. The quality of development came down with less top quality photos (mean 55%) and more poor quality and waste photos (mean 45%). The photos' lost fee was 500 yuan and the invisible economic waste was 900 yuan caused by developing in dark room per investigation. Because mobile camera bellows was linked with X ray photographing, the top grade rate of development raised 36% (mean91%), all kind of lost fee was only 62 yuan these years, manpower, material resources and financial resources were saved through remedying poor quality photos and waste photos.
