Storage Phosphor System For Computed Radiography: Screen Optics

A model for light scattering and absorption effects is applied to a system for computed radiography in which a turbid photostimulable phosphor is scanned with a laser. The spatial spreading of the laser light and the escape probability of the stimulated light are important in determining system response, and models for their effects are presented. Model calculations of system MTF are compared with measured data.

Storage Phosphor System For Computed Radiography: Destructive Scanning

A particular system for computed radiography uses a photostimulable phosphor which is scanned by a laser that reads and also erases the storage medium. The process of reading and erasing is called destructive scanning, and a model of its effects is presented here. Model predictions of system dc gain vs. scanning exposure for the case of raster scanning with a Gaussian beam are compared with measured data.
