Abstract:
1. A computed radiography system, comprising a stimulating light source, a photostimulable glass imaging plate (PGIP) substantially transparent to the stimulating light positioned such that the stimulating light impinges said PGIP perpendicularly thereto producing photostimulated luminescence light (PLL) having a wave length different from said stimulating light source, a light collector having a light reflecting inner surface proximate said PGIP for collecting PLL emitted from said PGIP and having a hole or slot therein for admitting stimulating light into said light collector and onto said PGIP, an optical filter in communication with said light collector for blocking stimulating light waves and passing PLL therethrough, a light detector for receiving PLL from said optical filter and said light collector, a mechanism providing relative movement in two orthogonal directions between said PGIP and said stimulating light source while maintaining the perpendicular relationship between the PGIP and the stimulating light, and a mechanism including an analog to digital converter for converting the collected and detected PLL to a diagnostic readout.
