... about CR
The first CR system was put into use around 1983, however CR didn't become widely used until the '90's. The migration from analog film/chemistry took a large jump after 2000 and has continued through today. CR systems use very similar equipment to conventional radiography except that in place of a piece of film to create the image, an imaging plate (IP) made of photostimulable phosphor is used. The imaging plate is housed in a special cassette, however instead of taking an exposed film into a darkroom for developing in a chemical film processor, the imaging plate is run through a CR reader that uses a special laser-scanning process that reads and digitizes the image. The IP plates are re-useable and from what we can tell will easily provide quality images with over 10,000 scans...if properly taken care of.
