Computed Radiography I - Video Lesson

Hey, everybody, and welcome to the first video in a series on digital radiography. In this video, we will focus on the components of the cassettes used in computed radiography and how they work. Computed radiography or CR is a form of digital imaging that uses a cassette based system. Similar in many ways to conventional film based radiography. A thin active layer within a protective cassette records and stores the X-ray energy as an unprocessed image, much like the film in traditional radiography when exposed to X-ray photons. Just like with film images, This initial exposure results in only what we will call a latent image and still needs to be processed into a usable radiograph. In computed radiography, this process is done by a plate reader that will
