Advantages
*use gadolinium oxisulfide with terbium (Gd2O2S:Tb) for orhto-type phosphor emitting green light. (Toshiba Ortho Type)
*have high sensitivity and high sharpness by TOSHIBA technology that makes a high-density phosphor layer and prepares optimal grain size distribution.
*Sensitivity and sharpness are further improved by structural designing that ensures effective light reflection and X-ray absorption characteristics.
*The surfaces are protected with a special film to prevent darts and scars and to render handling easy.
