What is the main difference between analog and digital radiography?

The distinction between analog and digital radiography primarily lies in the method of image capture. Analog radiography relies on film to capture images, a conventional method that has been used for many years. In this process, X-rays are absorbed by the film, producing a latent image that must be developed using chemical processes. On the other hand, digital radiography utilizes electronic sensors to capture and convert the X-ray images directly into digital format. This method allows for quicker image processing, enhancing workflow and efficiency in medical settings.

The choice of using film versus electronic sensors is significant as it affects how images are stored, processed, and displayed. Digital radiography also offers advantages like the ability to manipulate images post-capture and the ease of sharing files electronically, which are foundational benefits that modern radiology departments are capitalizing on. This understanding illustrates why the main difference is centered on the technology used for capturing images, distinguishing between the analog film-based approach and the digital sensor approach.
