Introduction to x ray imaging

WebAug 31, 2024 · Plain Radiographs. Plain radiographs, also known as x-rays or plain films, produce two-dimensional images. X-rays are generated by the machine and directed towards the subject (e.g. a wrist or chest). The detector on the other side of the subject is a piece of film or (more commonly) a digital plate. WebDigital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance …
