Which of the following describes digital radiography?

A film-based imaging technique
An analog radiographic system
A filmless radiographic computer imaging system
A manual imaging process

The correct answer is: A filmless radiographic computer imaging system

Digital radiography is characterized as a filmless radiographic computer imaging system that captures and processes images electronically rather than using traditional film. This technology allows for immediate image acquisition, reducing the time required to develop images compared to film-based systems. In digital radiography, sensors convert the radiation exposure into digital signals that can be displayed, stored, and manipulated using computer software. This enhances the diagnostic capabilities by allowing practitioners to adjust image contrast and brightness, improving the visibility of details that may be obscured in film images. The use of digital technology not only streamlines the workflow in imaging but also eliminates the need for chemicals and physical storage associated with film, making it more environmentally friendly and efficient. Thus, this option accurately describes the essence and advantages of digital radiography.
