Abstract
A luminescent storage screen, in which a latent x-ray image is stored, is read-out using stimulating radiation at a first wavelength, which causes light at a second wavelength to be emitted by the screen. The stimulable phosphor is transparent in the range of the two wavelengths. The stimulable phosphor is a doped alkali halide, such as a thallium-doped rubidium-bromide.
Claims7
A method for manufacturing a transparent stimulable phosphor for use in a luminescent storage screen comprising the steps of:
- vapor-depositing a stimulable phosphor in a high vacuum on a carrier;
- and
- re-tempering the vapor-deposited stimulable phosphor under a protective gas atmosphere up to a temperature slightly less than the melting point of the stimulable phosphor.
A method for manufacturing a transparent stimulable phosphor for use in a luminescent storage screen comprising the steps of:
- pressing a stimulable phosphor on a carrier under elevated temperature.
A method for manufacturing a transparent stimulable phosphor by pressing a stimulable phosphor on a carrier in a vacuum.
