Computed Radiography involves equipment that is similar to conventional radiography. Instead of using film to create the image, however, an imaging plate made of photostimulable phosphor is used.

The photostimulable phosphor imaging plate is then put through a laser scanner, called a CR reader, to both read and digitize the image. At that point, the image can be viewed using specific software where zoom, contrast, brightness and filtration can all be adjusted for better evaluation.
There are many advantages to using Computed Radiography. Film can be processed without chemicals. Images can be stored digitally reducing storage costs and making transportation for off-site review very easy.

Fewer retakes are necessary with Computed Radiography so it’s safer for patients because they are exposed to a lower dose than in other forms of x-ray. Previews of images are available in as little as 15 seconds and interpretation is significantly improved because images can be enhanced digitally.

Computed Radiography differs slightly from similar Digital Radiography technology. While both similarly use a medium of some sort to capture x-ray energy, computed radiography uses a cassette inside of which is the imaging plate that records the image. In Digital Radiography, on the other hand, the image is captured directly onto a flat panel detector.

Computed Radiography systems are most often found in the medical field because they are considered to be extremely reliable having been in use in the field for over twenty years. They are also flexible enough to have multiple clinical applications and provide a lower cost, digital alternative.

Computed Radiography is becoming more affordable and eco-friendly. For the same cost as staffing a conventional x-ray lab, including purchasing chemicals, providing dark room storage and paying staff, Computed Radiology does the same job and is far gentler on the environment and on patients as well.
