Toshiba Intensifying Screens
Outline
Intensifying screens are made of highly sensitive phosphors and used with photofluorography. When we are X-rayed, they reduce irradiation to one hundredth of the ordinal irradiation without intensifying screens.
Advantages
-
Our intensifying screens have high sensitivity and high sharpness by our technology that makes a high-density phosphor layer and prepares optimal grain size distribution.
-
Sensitivity and sharpness are further improved by our structural designing that ensures effect ive light reflection and X-ray absorption characteristics.
-
The surfaces of intensifying screens are protected with a special film to prevent darts and scars and to render handling easy.
Types and phosphor materials of intensifying screens
-
Types and phosphor materials of intensifying screens
TO-type screens use gadolinium oxisulfide with terbium (Gd2O2S:Tb) for orhto-type phosphor emitting green light. (Toshiba Ortho Type)
-
E- and D-type screens use calcium tungstate (CaWO4) emitting blue light.
-
Q-type screens use barium fluoro chloride with europium (BaFCl:Eu) emitting blue light
