Direct and Indirect Digital Radiography - Video Lesson

Hey, everybody. Welcome back. In this lesson, we'll be discussing direct and indirect conversion digital radiography, also known as DR. Direct and indirect conversion digital radiography are different from computed radiography in that they do not use cassettes or stand alone cassette readers. Additionally, the image processing step follows the image acquisition immediately converting the radiographic image into digital data without an operator's involvement. Computer radiography requires the extra step to extract the latent image from the cassettes. So by eliminating these extra steps, digital radiography systems are faster and can produce higher quality images than computed radiography. DR requires X-ray images in one of two ways, either using direct conversion, which converts X rays to electronic
