Application of Window Width and Window Level of Computed Radiography Technology

Objective To investigate the basic parameters of window width and window level of computed radiography technology. Materials and Methods 1 000 Cases including 200 cases of chest,200 cases of waist,200 cases of neck,200 cases of abdomen and 200 cases of calf. All were examined by the machine of FujiFilm FCR XG-1. The application is Surpass Archire of ShangHai Surpass Technology co.,Ltd. The printer is FujiFilm DRY PIX 3000.Radiogragh quality evaluation tally with the standard of X-ray first rate. Results Window width of chest is 3 602±426 and the window level is 1 291±146, window width of waist is 2 880±367 and the window level is 1200±182 ,window width of neck is 2 480± 312 and the window level is 1 399±145 ,window width of abdomen is 2 221±454 and the window level is 893±142, window width of calf is 2 416±304 and the window level is 1 528±162. Conclusion The proper window width and window level can display the different level of the Reign Of Interesting(ROI) of the image ,and can acquire more information for clinical diagnoses.
