Varex Flat Panel Detector – XRpad 4343F

The Varex XRpad™ 4343 F is a lightweight, cassette sized flat panel detector for digital radiography. It fits into a conventional table or wall-stand Bucky, just like a film-screen cassette. Featuring a 18.7 million pixel image matrix, a best-in-class 100 μm pixel pitch, and a direct deposited CsI scintillator, the Varex XRpad 4343 F provides exceptional image quality. True 43 × 43 cm imaging area is provided, along with single-piece carbonfiber construction for the front and back housing which allows for easier placement and cleaning. Automatic Exposure Detection simplifies integration.
