Flat-Panel Detector vs Image Intensifier (Fluoroscopy)

A two-column comparison of a conventional image intensifier and a digital flat-panel detector in fluoroscopy. The image intensifier has a circular field with pincushion and S-distortion plus vignetting, present veiling glare, a narrow dynamic range that saturates and burns out bright areas, and lower contrast resolution. The flat-panel detector has a rectangular planar field with no geometric distortion, minimal veiling glare, a wide near-linear dynamic range of about ten thousand, and better contrast resolution. Detective quantum efficiency is broadly comparable between the two.
