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
