Computed radiography, or CR, is a digital image[1] acquisition and processing system for radiography that uses computers and laser technology. It was developed in the mid-1980s. CR images can be recorded on laser-printed film or transmitted and stored digitally. This technological change has a significant impact on hospital operating costs and efficiency because radiography is the most common method of diagnostic imaging. It accounts for 70% of all imaging procedures, in comparison to 10% for CT scans and 6% for MRIs.

The purpose of CR is to produce accurate radiographic images without the use of film, thereby streamlining the storage, display, and transmission of patient data. Because CR allows the radiographer to correct images immediately following exposure, the need for retake exposures is dramatically reduced. In a CR system, corrections made in the image are ...
