Phosphor imaging systems

The following TLC applications cited by PerkinElmer for the Cyclone Plus are typical of other phosphor imaging systems imaging of H, I, C, P, E, Tc,... 

Phosphor imaging systems [e.g., Fuji (available from Raytest), Molecular Dynamics, Packard] employ a sensitive, two-dimensional phosphor storage or imaging plate (IP) coated with a microcrystalline phosphor (BaFBr Eu ), which is exposed to the layer as in conventional autoradiography. The IP accumulates and... 

As discussed in connection with (2.2), (2.4) and (2.5), the gain, affects both the sensitivity and noise of the imaging system. It is important that the light produced from the phosphor is collected efficiently. If an inadequate amount of light is measured from each interacting X-ray, then the image will contain additional noise above and beyond the quantum noise, causing the SNR and DQE to be reduced. 

After the gel is dry on the Whatman paper, wrap it completely in plastic wrap. Expose the wrapped, dried gel to an X-ray film or phosphor imaging plate. Develop using an appropriate system.
