CR vs. DR in a nutshell Once you have decided that digital radiography makes sense for your veterinary practice, you have two classes of options that are available to you. These are computed radiography (CR) and direct digital radiography (DR). An introduction to CR Computed radiography systems were first introduced in the 1980’s. With CR systems, the film, intensifying screen, and cassette used in traditional radiography systems are replaced with an imaging plate. The imaging plate has a similar look and feel to a traditional film cassette. The wet film processor used in conventional radiography is replaced with a digital imaging reader. These imaging readers can have various shapes and sizes depending on the manufacturer. With CR the overall feel and workflow of acquiring an image is very similar to traditional film. As is the case with film, the CR cassette is placed in the bucky and an exposure is made. The imaging plate is then removed from the bucky tray and placed in an imaging reader. Inside the imaging reader, the imaging plate is exposed to a series of laser lights that read the information on the plate and a radiograph appears on a computer monitor. (If you were wondering this conversion to light represents and analog process so computed radiography is not, technically, completely digital.) The imaging plate is then "erased" inside the imaging reader and is ready to use for another exposure. This entire processing step takes about 60-90 seconds per image. It should be noted, however, that although the overall processing time is similar to traditional film you must remember that for all of the common systems on the veterinary market, you can only put one plate in at a time.
