Film-based X Ray Detectors use photographic film to capture the X-ray image. The X-ray photons pass through the body, and the film records the intensity of the X-rays that pass through it. The film is then developed to produce a visible image of the internal structure of the object. However, this method has several limitations, such as low sensitivity, limited dynamic range, and the need for chemical processing. Image intensifiers are electronic devices that amplify the light emitted from a phosphor screen when struck by X-rays.
The image is then projected onto a camera or a video screen, producing a bright image of the internal structure of the object. Image intensifiers are commonly used in fluoroscopy, a medical imaging technique that uses X-rays to obtain real-time images of the body's internal structures. These detectors play a critical role in medicine, science, and security. X Ray Detectors come in various types, including film-based detectors, image intensifiers, photostimulable phosphor (PSP) detectors, computed radiography (CR) detectors, and digital radiography (DR) detectors. Each of these types of detectors has its unique properties and applications.
