Digital Radiography Vs. Computed Radiography:  What’s The Difference?

Numerous advancements can be seen in the medical industry, including the technologies that are used in radiography. Accuracy is significantly increasing, resulting in early diagnosis of various conditions. As these devices continue to advance, better precision also makes it possible for surgeons to use less invasive procedures. There are two primary options available when it comes to using a modernized radiography system in your practice. This includes digital radiography and computed radiography devices. Let’s look at the differences between them.

Operating Principles Of A CR And DR System

Both digital and computed radiography provides imaging technologies that allow for the diagnosis of various diseases. The main aim of these devices is to provide a view inside the body without the need for incisions.

Computed radiography uses a Phosphor Imaging Plate, which assists in the creation of a digital image. Cassettes are used in order to record content, which has similarities to classic analog films. Many people consider computed radiography to be a middle point between digital radiography systems and classic options

A DR system is a more recent advancement and has a digital detector that takes x-ray images. The images are automatically obtained, and some of the latest models even allow for mobile usage. A DR system has superior efficiency and can provide greater quality images that help to improve the accuracy and preciseness of a diagnosis.

The Differences Between CR and DR Technologies

There are numerous factors that differentiate a DR system from a CR system:

  • Flexibility: A DR system can come in various shapes and sizes, making them more flexible in various settings. CR systems are not as mobile and portable, and may not have the same usage options compared to a DR system.
  • Imaging Quality: By assessing images from CR and DR systems, it’s clear that a DR system offers much clearer visuals that are more precise.
  • Safety (Dose of radiation): Radiation is a common concern in medical imaging testing procedures. The level of radiation has been significantly lowered in DR systems, even when compared to a CR system.
  • Efficiency: While more expensive, a DR system can make your workflow more efficient. The use of a flat panel detector means no more handling cassette tapes.
