A flat panel detector (FPD) is a digital imaging component used in radiography systems to capture X-ray images and convert them directly into digital data. It replaces traditional film or cassette-based systems, enabling faster image acquisition and higher image quality.
DR (Digital Radiography) systems use flat panel detectors to capture images instantly and display them directly on a computer screen. They offer faster workflow, lower radiation dose, and higher efficiency.
CR (Computed Radiography) systems use imaging plates (phosphor plates) inside cassettes. After exposure, the cassette must be processed in a separate reader to convert the image into digital format, making the process slower compared to DR systems.
In summary, DR systems provide real-time imaging and higher efficiency, while CR systems offer a more cost-effective transition from analog systems but require additional processing steps.
