Document Type and Number:
WIPO Patent Application WO2005048287
Kind Code:
A3
Abstract:
A phosphor screen comprises an inorganic phosphor capable of absorbing X-rays and emitting electromagnetic radiation having a wavelength greater than 300 nm. The phosphor is disposed on a support that has a reflective substrate (11) comprising a continuous polyester first phase (12) and a second phase dispersed within the continuous polyester first phase. The second phase contains microvoids (14) that in turn contain barium sulfate particles (16). This support provides improved reflectivity particularly at shorter wavelengths.
