Computed Radiography (CR) Systems in Sao Tome and Principe
Available Computed Radiography (CR) Systems Models

Computed Radiography (CR) systems represent a significant advancement in diagnostic imaging, offering a digital alternative to traditional film-based X-ray. At its core, a CR system utilizes reusable imaging plates coated with a photostimulable phosphor material. When X-rays pass through a patient's body, the phosphor plate absorbs and stores the energy, creating an 'image latent' within the plate. This plate is then fed into a CR reader, where a laser beam scans the surface. The scanned phosphor releases the stored energy as light, which is captured by a photomultiplier tube and converted into a digital signal. This signal is then processed by specialized software to reconstruct a high-quality digital radiographic image that can be viewed, manipulated, and stored electronically. Unlike direct digital radiography (DR), CR requires a separate plate reader step, but it offers greater flexibility and a lower initial investment compared to full DR systems.
