Digital X-ray replaces the use of film or computed radiography (CR) plates with a direct digital transfer of X-ray images into the PACS. Digital radiography (DR) is the direct conversion of transmitted X-ray photons into a digital image using an array of solid-state detectors such as amorphous selenium or silicon, with computer processing and display of the image. DR X-ray systems are used for both fixed base room installations and mobile DR, or portable DR, systems that are wheeled between room for imaging exams. Here is a link to the portable DR systems product comparison chart. Here is a link to the DR Systems chart that includes fixed room based systems and retrofit systems to replace film and CR.
Advantages of digital X-rays
Digital X-rays have several key advantages over other options:
- Real-time enhancement
- Reduces radiation exposure
- Avoids the use of chemicals for developing film
