Technical Note 53 Storage Phosphor Screens Technical information describing the performance characteristics for the Molecular Dynamics storage phosphor screens is provided in this note. This information is general and should not be considered as performance specifications for the screens. Stimulation Spectrum Stimulation is the process of releasing the stored information. The post stimulation decay has a time constant less than one sec. Ambiant Radiation Background Effect Screens were erased and then stored at room temperature in the Molecular Dynamics exposure cassette prior to scanning.
Ambient radiation is assumed to be environmental gamma rays.
The remaining signal must be erased before the storage phosphor screen is reused. As shown by the stimulation spectrum, the most efficient wavelengths of erasing light are between 475 and 650 nm. Actual flatness will vary with temperature, relative humidity and screen size. The aluminum mounting plate is flat to 0.005 inches. Molecular Dynamics Please read our Legal Information.
