Flat-panel detector

A flat-panel detector (FPD) is a type of imaging device primarily used in medical radiography and fluoroscopy, as well as in industrial applications. It serves as an electronic sensor that converts x-ray photons into a digital image, allowing for high-quality images to be captured quickly and efficiently. ### Key Characteristics: 1. **Structure**: Flat-panel detectors typically consist of a rectangular flat panel that houses an array of sensors, most commonly made of either amorphous silicon or selenium.
