Whether you are a practicing medical professional who owns and/or is looking to buy a new digital X-Ray system for your facility, or someone who is simply interested to learn more about the latest imaging technologies, you must have heard about digital imaging systems like Computed Radiography (CR) and Digital Radiography (DR).
With ongoing technological advancements and significant cost reductions with regards to purchasing, processing and storage of traditional film, digital X-ray systems have rapidly become the preferred choice amongst many healthcare professionals.
While both CR and DR imaging techniques use digital technology for X-ray imaging and pose significant advantages over the traditional screen-film radiography, what is the difference between DR and CR X-rays? And which would be a better choice for your practice?
Before making a decision, let us first understand the process of Computed Radiography and Digital Radiography separately, followed by a comparison between them.
What is Computed Radiography?
Sometimes known as “Film-replacement Technology”, Computed Radiography (or CR) is an imaging technology that uses a flexible phosphor imaging plate (IP) to capture image, and create a digital output instead of using conventional films.
CR systems require minimal changes to be made in an imaging facility, and are also widely known to be an “initial” cost-friendly solution. However, CR systems do not allow to speed up the workflow, and requires frequent maintenance. In addition, there is a risk of over-exposure while using a CR system.
What is Digital Radiography?
Digital Radiography (DR) is the latest advancement in radiography. It uses X-ray sensitive detectors that quickly transfers & displays the image onto a computer, so the user can view and diagnose without an intermediate cassette.
DRs generally have better signal-to-noise ratio and an improved dynamic range, which, in turn, provides high sensitivity for radiographic applications. These systems are additionally capable of either mobile or fix use – making it more flexible for varied applications.
While the initial investment for a DR system may be high, its output quality, workflow efficiency, less frequency of maintenance and other advantages outweighs the cons, thereby making DR the fast preferred choice of digital X-Ray systems among many clinicians.
What is the difference between CR and DR X-Ray Systems?
Although CR and DR systems require far less exposure time than the conventional Screen-Film Radiography, Computed Radiography is an older technology as compared to Digital Radiography, with DR possessing significant advantages over CR systems.
There are several factors to consider when deciding whether CR or DR best suits your needs. For that, let us understand the major differences between DR and CR against various parameters, and how is DR better than CR (Advantages of DR):
Parameters | CR System | DR System | Advantages of DR |
---|---|---|---|
Components | CR Scan Unit, Cassettes and PC Workstation | Flat Panel Detector and PC Workstation / Laptop / Tablet | DR allows portability whereas CR is a fixed system and bulky in size |
Image display time | 6 – 8 minutes | Within few seconds | More patients can be scanned in lesser time |
Method of Scan | Cassette to be exposed & inserted to the CR Reader | Instant image retrieval & display after exposure |
|
Material Used for Exposure | Cassettes uses Phosphor material | Directly deposited CsI scintillation material offers higher DQE: 65% |
|
Image Quality | CR is more sensitive to artifacts as Image Plate of Cassettes easily gets wear & tear | Detector doesn't have issue of scratches and offers better image quality at lower dose |
|
Portability | Multiple cassettes to be carried to different departments for all cases | With one detector and mobile kit all the cases could be completed |
|
Maintenance | High maintenance cost , cassette / image plates to be replaced frequently | Unit comes only with panel and workstation |

I recently read this article about DR and CR X-RAY SYSTEMS, and it was very informative. It provided a lot of helpful information on the differences between the systems, and how to choose the right one for my specific needs. I appreciated the fact that it was written in an easy to understand way, so that even someone with no prior knowledge of X Ray machines could understand.
